A while back, Sam over at Look Mum No Computer did an examiner/recreation of the early 1970s automated music system, the Psych-Tone. Designed by the legendary Don Lancaster and first appearing in the February 1971 issue of Popular Electronics (and a kit made available by SWTPC, the Southwest Technical Products Corporation), the Psych-Tone used early logic chips and transistors to play a number of different tunes based on the setting of various switches and potentiometers.

The core of the circuit is a pseudorandom sequence generator — a circuit that creates a single random sequence of 0s and 1s, and keeps it circulating. With six stages in the chain, the sequence is 63 steps long. The three selector knobs each pick where in the chain to listen, and when that value is 1, pass that through a potentiometer to set a partial pitch. The three partial values sum together to make a tune, which is played on an organ-like tone generator.

In explaining the device, Sam built a new version of the machine's sequencer section, using slightly newer chips and adding some LEDs to illustrate the functioning, for folks to play on synths with at his This Museum is (Not) Obsolete. Which got me thinking about doing something similar myself — building essentially the note generator as a random sequence creator for Eurorack.

Fortunately, in addition to Sam's video and the original article, Lancaster wrote up how to build these PRSGs, in varying lengths, in his book CMOS Cookbook; where the original used individual flipflops, this updated circuit lets you use shift registers (since one of those is effectively an internally-connected string of flipflops). To boil things down, by feeding certain of the output values back to the input through an XOR gate, a n bit shift register can cycle through a 2^(n-1) sequence, which can then be used in a number of different ways — basically anywhere you want something that's effectively random, but potentially repeatably so.

The circuit diagrams and tables given there have let me breadboard up something that I haven't yet tested, for a few reasons.

First, I'm feeling a little unsure as to how long to make the sequence. Obviously, if you make the sequence too short, it's too repetitive, but conversely, if it's too long, it's not going to be distinguishable from randomness. The original's length of 63 steps seems short, but the breadboarded circuit right now is set up for not 6, but 16 stages, which would yield a sequence length of 65,535 steps, which might be a bit much.

That's not more than something to work out in testing, though, which leads to reason two. Like with Sam's version, the one on the breadboard is meant to show the internal workings by using LEDs. And I've got a couple of nice, compact 10-segment bar graph LED displays on the breadboard, each one wired to 8 of the 16 stages. But LEDs can't handle just being plugged into a raw voltage; each one needs a current-limiting resistor to keep it from burning out. And while I could hook up 16 separate resistors on this breadboard, I don't wanna. I have — someplace around here — a nice little assortment of resistor arrays, chiplike affairs where eight identical resistors all connect to the same ground pin. Once I find them, I can watch the blinkenlights and get a better picture of the kind of sequences I'm dealing with.

(Your basic pseudorandom sequence generator goes in one direction, while the Psych-Tone can also run the sequence in reverse; while the section from CMOS Cookbook is a little terse about how that's done, I think I have that figured out too. Unfortunately, changing directions on the fly requires some complicated switching, so it's hard to do with just hardware — though I just found a giant chunky switch in my collection that could be coerced into selecting forwards or backwards on three different sequence lengths — say, switching between 8, 12, and 16 stages? Hmmm.)

The actual translation from discrete stages of either 0 or 1 works first by selecting one of the stages, and connecting it to a potentiometer, wired as a voltage divider. When the stage is at 0, the pot's output is still 0v. But when the stage hits 1, the pot outputs a voltage between 0v and the "high" voltage level of the circuit, depending on where the knob is set. With just that, you've got a two-note output. If you add another selector with its own pot, and add the output voltages together, you've suddenly got four distinct values: 0v when neither is a 1, the ratio from the A selector when only it has a 1, the ratio from the B selector likewise, and A+B when both have 1s. Go to three selectors and you've got 8 values; four will get you 16 values.

(Well, assuming that A+B doesn't exactly equal C, or some similar arrangement that would reduce the actual possible values, and I'm intending to make a constant 1 selectable as well, so you could use it for tuning or as an offset. Because of how Eurorack tuning works, if you have A-C on different stages and D is always 1V, then the notes would be the same 8 as those for A-C but up one octave.)

Anyway. I am overexplaining a project that's barely begun, and I've been doing that for several hours while I should be trying to sleep, neither of which is a good sign. Perhaps tomorrow I'll find those resistor arrays and at least get things blinking.

There are 7 different types of leg press machines you need to know.

There are 7 different types of leg press machines you need to know.

Leg day is important to us. We love the part of the gym that people use to burn their legs.

You've probably heard about leg presses, but do you know how many different types there are?

You're in for a treat if that's the only thing you wanted to see!

This article will explore seven different types of leg press machines you should be aware of.

Leg press machines are great for building strength, power and muscle in the lower body, whether you're an experienced gym goer or you're just starting out.

There are leg press machines for every fitness goal and level.

Let's start and learn about the various types of leg presses that will help you to achieve a new level of fitness.

What are the different leg press machine types?

Click to skip to section

45 degree Linear Leg Press

The 45 Degree Linear Leg Press, a popular machine, allows users to push a sled with weight at a 45 degree angle.

The leg press machine that is commonly found in commercial gyms is a plate-loaded type.

Horizontal Seated Leg Press

Horizontal Seated leg press is a machine used while seated with legs out in front.

This type of machine is usually a pin-selectorized design and provides a more supported and comfortable leg press.

Angled Leverage Leg Press

The Angled Leverage Leg Press uses a lever system to provide resistance. This machine can be found in many gyms. It allows a controlled and smooth leg press with a wide range of motion.

Dual-Function Leg Press (Leg Press/Hack Squat)

Dual Function Leg Press Machine can be used both as a leg press or hack squat.

The leg press machine of this type is designed to fit into home gyms. It offers users more versatility and less space than two machines.

Vertical Leg Lift

The Vertical Leg press machine is a machine which allows the user to perform a leg pressing movement in a horizontal position while lying on their back.

The leg press machines are typically plate-loaded. They can be a great challenge for the legs while providing ultimate safety to your neck and back.

Compact Leg Press

Compact Leg Press machine is designed to be smaller than other leg press machines.

Leg press machines are often found in home gymnasiums. They can be used to provide a challenging workout for the legs in a small space and at a lower price.

Isolateral Leg Press

The Isolateral Leg Press Machine allows the user to independently work each leg.

Leg press machines are often found in commercial gyms. They can be used to correct leg imbalances, and provide a high level of isolation for advanced lifters.

45 Degree Linear Leg Press

The 45 Degree Linear Leg Press Machine, a popular machine, allows users to push weights on a sled with a 45 degree incline.

The machine is also known as incline leg presses, linear leg presses, or 90 degree leg presses. It gets its name because of the angle at which the tyres are positioned.

This type of leg presses can hold a lot of weight, and is often used in commercial settings.

The sled is straight and the user must focus on their lower body while maintaining a strong back and neck.

The 45 Degree Linear Leg Press sled is mounted on linear bearings which move along a fixed track. This helps provide a smooth, consistent motion.

The user sits with their backs against a pad, and their feet resting on a sled. This'sled' is then pushed outward to complete the leg pressing movement.

The 45 Degree Linear Leg Press comes with a plate that allows users to adjust the weight according to their resistance level.

How to use a 45 degree linear leg press

Here's a guide to help you use a 45-degree linear leg press effectively if you're a new user. The machines may vary in appearance, but they are generally used the same way.

You can adjust the weight of the machine to the desired resistance level.

As you sit, place your back on the pad with your feet on the sled.

Put your feet on the sled shoulder-width apart, your toes slightly pointing outward.

Slowly lower the weight of the sled towards your body by releasing the safety locks.

Straighten your legs and push the sled back away from you.

Repeat the desired number of reps by slowly lowering the weight towards your body.

45 Degree Linear Leg Press Benefits

Lower Body Isolation

This 45 degree linear leg press, like all other leg pressing exercises, will help you build strength and power in your legs by targeting your quads hamstrings and glutes.

There is Little or No Spinal Compression

The 45 Degree Linear Leg Press is a great alternative to traditional barbell squats. It can help reduce spinal compression and therefore be a better option for people with back injuries or pain.

Controlled Movement

The 45 Degree Linear leg press has linear bearings that provide a smooth, consistent motion. This allows users to remain in control during the entire exercise.

Customizable resistance

A plate-loaded machine allows users to adjust the weight according to their fitness level.

Pre-Cation Safety Built-In

In most cases, the leg press won't crush you if you miss a rep or if an accident occurs. Leg press machines are generally safe to use, even though it is best to avoid them.

Horizontal Seated Leg Press

The horizontal seated foot press is a pin-selectorized machine which requires the user sit horizontally and either push weight forward with their legs, or push backwards from a stationary feet plate.

It is very easy to mount the horizonal version. You just need to sit on it, and press.

It is easy to switch weights from one set or user to another with the selectorized weight stack included in the machine.

It is perfect for beginners or rehab clients, as you can limit the depth of the machine (range-of-motion) in order to reduce any risks.

The safest machine of the lot is this leg press.

How to use a horizontal seated leg press

When you press, adjust the seat so your knees are roughly at a 90 degree angle.

Choose the weight you would like to use for leg press by using the weight stack.

Put your feet about shoulder width apart on the platform or wherever you feel comfortable.

Grab the handles at the side of the machine to ensure stability.

Push your feet into the footplate, using your quads to push, while keeping your glutes tight and your core in place.

Perform as many repetitions as you like by slowly lowering the weight to the starting position.

Horizontal Leg Press Benefits

Targeted muscle development.

The horizontal seated leg presses primarily target the quadriceps, but also work the hamstrings.

Low Impact

The horizontal seated leg presses are low-impact exercises that put minimal strain on joints.

Easy to use

It is easy to change the weight or switch users with this pin selectorized system.

Adjustable Range of Motion

The design of the machine allows for greater flexibility, as it can increase over time.

Leg Press with Angled Leverage

A Leg Press with Angled Leverage is a machine that uses a system of levers to provide resistance for the user.

This machine is usually plate-loaded and has a 45-degree incline. It offers a lot of resistance and adjustability.

The angled leg press is named so because it has a range of motion that is angled to some extent.

The design is based on a biomechanical range of motion that targets the quads and hamstrings most effectively, with little or no involvement of the upper and lower back.

The leg press works well for all-around strength and muscle growth in your legs, with an emphasis on hypertrophy.

How to use a Leg Press with Leverage

Start by adjusting your seat to the desired position. Then, load the weight plates you know you will be able to perform multiple reps.

Set your foot position by seated on the machine, with your back flat against the backrest of the machine and your feet on the footplate.

Grab the handles on either side of the seat, brace your core and legs, and then release the safety device, which is usually located on the side.

Squeeze your quadriceps while pushing the footplate with your feet.

Remember to keep your knees from being fully extended for safety.

Regroup yourself for the next rep. Remember to breathe!

Benefits of Angled Leverage Leg press

Supreme Range Of Motion

It is well known that the angled leg press has a wide range of motion. This allows for a full contraction on top and a deep stretch in the legs.

Lower Body Isolation

The angled leg presses place very little stress on your lower and upper back. This allows you to focus all of your energy in the legs, which leads to a high level hypertrophy and development.

Isolated Leg Exercise

By pressing one leg at a given time, you can correct muscle imbalances. The great range of motion of this type of leg press makes it popular for isolation exercises.

Fits Different Fitness Levels

Leverage leg presses are suitable for people with varying fitness levels and abilities, as they offer adjustable resistance and ranges of motion.

Very Low Injury Risk

Leverage angled leg presses are safer than traditional squats because there is no weight placed on the shoulders or back.

Dual Function Leg Press (Leg Press/Hack Squat).

Dual Function Leg Press Machine allows you to do both hack squats and leg presses. It is an excellent addition to any home or gym workout area.

The machine usually includes a footplate and a back plate which can be adjusted for different sizes of bodies and to accommodate various exercise variations.

You can switch between an incline leg press at 45 degrees and a shoulder-loaded hack squat in the same machine without having to spend extra money or space.

How to use a dual function leg press / hack squat

1. Adjust the machine to fit your body.

2. You can load up the machine with as much weight you want to achieve optimal resistance. These machines are usually plate-loaded.

3. Before you begin, brace your legs, glutes, and core. Also, disengage the machine's safety mechanism.

4. You can choose to move at any time.

Dual Function Leg Press Benefits

Versatility

This machine has two functions that allow you to do two popular lower-body exercises in one machine.

Adjustable Plate Loaded Resistance

You can add or remove weights to the machine to adjust resistance according to your fitness level.

Low Joint Strain

Leg press and hacksquats performed on this machine are less stressful on the knees, hips and lower back than traditional squats and lunges. This makes them an excellent option for most people.

Save Money and Space

By combining these two machines, you can save space and money for your home gym or facility.

Vertical Leg Press

Vertical leg press has a different design than other leg presses.

The machine is vertically aligned, as its name suggests.

The pushes up the platform by laying flat on the ground with the back of the person against the padded support.

It is important to maintain the neck and back in a neutral position and aligned for safety.

This is a great machine to add to your routine as a change from the usual leg press machine.

How to use a vertical leg press

1. Start with a small amount of weight and work your way up. Start light and gradually increase your weight to determine your strength capacity.

2. Place yourself comfortably in the machine by lying flat on your back.

3. Put your feet on the machine in a position where you can achieve the full depth without having your heels or feet rise above the footplate.

4. Engage your legs and brace your core, then de-engage the safety device on the machine.

5. As you resist the weight, bend your knees outwards and push them towards your core. You should stretch out fully but not so deep that you end up stuck at the bottom.

6. Drive the footplate back upwards, while keeping your core braced. This is one rep.

Vertical Leg Press Benefits

Unique Leg Press Movement

The vertical leg press may not be something that everyone is familiar with. Try it out and you will be surprised at how different it is from other machines.

Lower Back and Neck Support

The lower back, upper spine, and neck are all almost entirely left out. You will feel the stretch in your hamstrings and glutes without having to strain your back.

Direct 1 to 1 Weight Ratio

Some leg press machines, such as the 45 degree leg press or the leverage leg press have a weight slightly higher than what you actually feel you are pushing.

Gravity and the angle of the machine combine to make it appear smaller than it is.

If you align the machine vertically, the weight that you place on it will be met with 100% of its resistance, not a slight angle.

Different Types of Leg Press Machines

There are many different types of leg presses, all with their own benefits and features.

Consider factors like the weight range, machine dimensions and user experience when choosing your best option.

The best leg press machine will be one that suits your fitness goals and preferences.

How To Do a ‘Work In’ Workout So Someone Using the Equipment You Want Is Never an Exercise Stop Sign

You’ve taken your pre-workout supplements, picked out your playlist, and you’re know you’re about to crush your training plan… only you get ready to start, and every machine and set of free weightsat the gym  is taken. Now what do you do? You could wait around for things to open up, but who knows how long that could take. Or you could ask someone if you can do a work-in workout with them. For the unfamiliar, a work-in workout is when you share weights or machines with another person in the gym and while they are doing their sets you rest, and vice versa. “Typically, when we talk about working in, it will be on the strength floor with selectorized machines—where you put a pin in a weight stack—plate loaded machines with barbells, or dumbbells,” says Jana King, certified personal trainer, and president of Lifestyle Coordination studio in Los Angeles, California. “Because about one to three minutes of rest is typically needed between sets when strength training, it makes sense that two people can work on the same equipment by alternating their rest and work periods without either person being inconvenienced.” How to ask someone if you can work in with them When deciding on whether or not to work-in with someone using a machine or weights you’d like to use, King says it’s best to observe first. “Before approaching, watch the person do at least one set and wait until they start their rest to approach them,” she says. When you do make the decision to ask someone if you can work-in, King suggests acknowledging the person first with an ice breaker before asking them how many sets they have left—a typical number of sets is anywhere from two to five, she says. If they only have one set left, you can wait for them to finish up, but don’t rush them. On the flip side, don’t feel rushed if you’re the person with one set left, but do be considerate to the person waiting.  If they have more than one set, King says there are a few things to consider before asking, “Do you mind if I work in with you?”  to make sure the workout works for you both.  How to pick the right person to tag team with There are two important things when picking the right work-in partner to make the most of your time. First is to gauge if you can use the same weight and/or how difficult it would be to load/unload plates in order for you to work in. The second is to check out the height of the other person, depending on the type of equipment you are using because you don’t want to have to move the height of the barbell in a squat rack up and down between each set, for example, becasue it’ll eat up time and make both your workouts less efficient.  “If you are the person who has the first right to the barbell or machine, it is acceptable for you to deny a work-in in this scenario, but again, be considerate that someone is waiting and try to keep further use to five to 10 minutes at a maximum,” King says. Proper etiquette for a work-in workout Once you’ve found a person that will allow you to work-in with them (woo-hoo), the most important thing is to be a courteous partner. Remember the Golden Rule, and treat others how you want to be treated. “Between each set you are returning the equipment back to the original condition of the person who was there first,” says King, who adds that you should wipe down and disinfect the equipment after you’re finished before trading off.    Sharing space and working in together allows everyone to keep moving forward toward their fitness goals as efficiently as possible. Just be sure that you’re approaching people who are roughly at your fitness level (and height) and being polite when you ask them in your can work in with them. “Working in isn’t difficult,” King says, “especially when done with respect.”  Read the full article

scope restore part 3

so it is time for some serious troubleshooting.  now personally I’ve never actually encountered a cold solder joint. but if there was going to be one it would probably be inside of this old ass barn scope. so after consulting the fully dutch manual and reseating the tubes for good measure. I got a schematic for it’s power supply and was able to test for voltages from the transformer. and they would come alive and go dead seemingly at random.  ٩(ఠ益ఠ)۶

it was strange because it would either have 120v on the primary side when it was on or it would have basically 0v on the primary side when it was on yet draw 0 current???  (＠_＠)   I’m writing a complaint letter to georg ohm as we speak 

after a few hours of desoldering and resoldering everything connected to the primary side of the transformer (inculding a very neat mains voltage selector switch with 110,125,145,200,220,245 volt options; making this scope pretty much able to be powered on from any socket in the world. (yet still only having a dutch manual available)) I dicided to say fuck it and just remove the whole damn transformer to test if there was some sort of short/ open winding. 

it tested good which was a relief and so to celebrate I got rid of a lot of unnessary bs in the circuit like the mains voltage selector, a weird 3 pin input connector at the back and these totally broken testing switches that can be seen in the bottom of the second pic. yippe ! less failure points.  (* ^ ω ^)

I resoldered and mounted the transformer back into the machine and gave it a test and it WORKS  NOW !! (not like fully actually working but like it turns on and gives trace)

so things are good. it turns on and seems to react to a change in voltage at it’s inputs appropriatelyish. no proper horizontal movement tho, but that only gives me more fun things to fix. couldn’t be that easy right?

so step 4 is going to be replacing all of it’s many black beauty capacitors  ( https://w140.com/tekwiki/wiki/Bumble_Bee_capacitors ) that have surely gone bad by now along with some drifty carbon composite resistor enamies.    (งಠ_ಠ)ง　

 so now I just have to wait for the replacements I ordered.

Lower Body Workout Using Selectorized Machines

Selectorized, or pin selector, machines are great to use at all fitness levels.

The Steyr M.1912/P16 machine-pistol

This weapon was reportedly commissioned at the end of 1915 and developed at the Österreichische Waffenfabriksgesellschaft under the direction of Major Franz Xaver Fuchs, commander of Standschützen-Bataillon Innsbruck II. Major Fuchs was, curiously, a painter by trade, not an engineer. Prior to the war, he tutored at the Franziskanergymnasium in Tyrol. Interestingly, another Standschützen officer - one Herr Hellriegel - also developed a submachine gun-type weapon that was tested in Tyrol in late 1915, implying that there was some interest in machine-pistols and SMGs within Tyrolean Standschützen regiments in particular. The exact reason for this is not entirely known although it is likely that they realized from an early date that light automatic weapons would be required in an alpine conflict with Italy.

The M.12/P16 machine-pistol was an automatic conversion of the standard Steyr M.12 service pistol, and the operation was unchanged, incorporating a short recoil action in which the barrel and slide recoiled together until the barrel was forced into a 20° rotation by two locking lugs until the slide returned forward. The only technical difference between the standard M.12 and the M.12/P16 was the addition of a fire selector switch which allowed uninterrupted automatic fire, situated on the right side of the trigger group. The selector mechanism basically consisted of two 'arms' - a long 'arm' which was the selector switch itself, and a short 'arm' which acted as a trigger link - both pinned to the trigger group by connecting screw. The screw passed through the selector switch first, the trigger link second, and the lastly the trigger itself. The bottom of the trigger link was itself pinned to the trigger piece. When the selector switch was flipped up, the screw would turn and drag the trigger link backward, which in turn would place pressure on the trigger itself and hold the sear down. Thus, when the trigger was pulled fully, the pinned-down sear would be prevented from interrupting the action. This gave an automatic fire rate of about 800 rounds per minute.

By February 1916, a batch of 50 prototypes were delivered for field trials and were issued to Major Fuchs' battalion. These early models fed from the M.12's standard 8-round internal magazine and, against a firing rate of 800rpm, they could only fire off a short burst or two before depleting. This was somewhat remedied in the full production model, which extended the internal magazine to 16 rounds - an improvement, but still less than ideal. Topping off the magazine, either by feeding two 8- round clips or manually loading each cartridge by hand, was also slow and cumbersome compared to a detachable magazine feed. It is because of this extended magazine that the weapon earned its "P16" suffix, standing for Patrone 16 ("16 cartridges") - contrary to some reports, "P16" is not in reference to the year 1916.

After a successful trial phase, the M.12/P16 was accepted into service, reportedly with an order of some 5,000 units being placed. They were issued exclusively on the Italian Front, to bolster the firepower of Tyrolean regiments fighting in the Alps. It is not known whether they were actually fielded as trench-clearing assault weapons as is commonly assumed; Austria in 1916 was fighting a mostly defensive war against the Italians, and there is no indication that the weapon was commissioned for use by shock troops, although it is certainly possible that they were issued to some Sturmbataillons in 1917.

As evidence of the Villar Perosa's influence on Austrian submachine gun concepts, a contraption was developed for the M.12/P16 known as the Doppelpistole ("double-pistol"). This was simply a double mount that fitted two M.12/P16s to a central wooden buttstock in an attempt to make it "double-barrelled". A wooden carrying case, similar to that issued with the Villar Perosa, was also made for the Doppelpistole, although the idea seems to have been experimental and never came into wide issue. It may have been intended as a fixture for aircraft.

The M.12/P16 remained in service throughout the war, and was apparently produced in surprisingly large numbers. An inventory taken in Tyrol at the end of the war reported some 9,873 units in issue. In spite of this, the physical evidence for such a large number having been produced is scant. Only a handful of examples exist today, most of which are low serial numbers, leaving some experts to have estimated that less than a thousand were made (Thomas Nelson claimed around 900). It is possible that most examples were destroyed by the Inter-Allied Commission after World War I, but this is merely speculation. The associated patent for the fire-selector was finally approved in December 1919, having been applied for three years earlier, although there is nothing to suggest that the weapon was ever produced again after the armistice. Claims that M.12/P16 machine-pistols were rebarreled in 9x19mm Parabellum and issued with silencers to Abwehr commandos in World War II are unverified.

I went to the gym at my apartment today during my lunch break, and none of the weight machines had the selector pins in them so they’re essentially unusable. Someone came into the gym as I was getting ready to leave and I asked about it and apparently they had been stolen a few weeks ago and not replaced yet but like why would anyone steal those I don’t understand????

1950 09 26 Seoul, Dog Company pinned down - Peter Dennis

On the morning of September 26, three US marine regiments, the KMC, a US Army, and an ROK regiment closed in on Seoul from the northwest, west, southwest, and south. To spearhead the 7th Marines’ advance, D/7 under Capt Richard R. Breen, was sent southwest on the Seoul–Kaesong Highway to secure the Sodaeman Prison on the northwest edge of the city. As D/7 approached Seoul between the steep slopes of Hill 296 on the right and Hill 338 on the left, they were greeted by cheering Koreans. The column was taken under fire from a water tower 400yd to the front and the civilians scattered. NKs then opened fire from the hillsides only 100yd away. The company deployed on both sides of the road returning fire, but was pinned down. The marines were unable to deploy flank security because of the civilian crowds. The company mortar section under 1stLt Paul P. Sartwell set up two 60mm mortars and immediately knocked out an enemy position. Totally exposed, the lieutenant directed the mortar fire and was hit three times before being put out of action. Two rifle platoons maneuvered to clear the slopes, but resistance was heavy. A tank-infantry relief force sent by the regiment was turned back. The company, faced with encirclement, all officers wounded, and casualties mounting, withdrew 1,000yd back up the road. The mortars delivered covering fire during the withdrawal. Carrying all of their dead and wounded, they established a perimeter on both sides of the road in the late afternoon. Before dark they received an airdrop of ammunition and supplies and prepared for a tough night. The NKs, though, contented themselves with remaining in their hill positions. The rest of the 2/7 was attacking eastward and the 3/7 also attacked east to secure a foothold on the north end of Hill 338. D/7 was relieved in the morning. Army and marine rifle companies were allocated an array of supporting weapons, but their distribution differed. A marine company had a machine-gun platoon of three sections, each with two squads armed with a Browning .30cal M1919A4 light machine gun. A section was generally allotted to each rifle platoon. Within the company headquarters was a mortar section with three 60mm M19 mortars. The marines concentrated 18 3.5-in. M20 bazookas in the battalion assault platoon, with two attached to each rifle platoon. Army rifle company weapons platoons had a mortar section with three 60mm mortars and a special weapons section with three 57mm M18 recoilless rifles (not used by the marines). Army rifle platoons had a weapons squad with a bazooka and an M1919A4 machine gun. The 60mm M19 mortar was the rifle company’s workhorse, its resident “artillery.” While artillery support was usually available, the benefit of the immediate fire that a company’s own mortars could provide was invaluable. The M19 was essentially the same as the M2 used in World War II, but was provided with a selector lever on the tube’s base plug allowing it to be drop-fired or trigger-fired. Some units deployed to Korea with the M2 and they were also issued to ROK units. Their ammunition was interchangeable with that of the Chinese 60mm Type 31. Ammunition included high explosive and white phosphorous smoke as well as illumination (parachute-suspended flares, not pictured). The maximum range was 1,985yd and its minimum was 50 yards.
