The smaller size of Soviet armored vehicles was not due to ignoring crew comfort, but due to this principal design philosophy: smaller size = less area to cover with armor = better armor for less weight + better mobility due to better power to weight ratio.

The old ship still exists as a museum and is in such a condition that she could still be used today. The main reason for the replacement was the huge size increase in Japanese men since 1930. 1980s japanese sailors simply were too big to fit her berthing decks.

Tankograd is an excellent resource and is very well written. I enjoy the Author’s work and these interviews a lot. That being said, as someone who has spend hundreds of hours in an Abrams gunners station and also been inside a T-72 equivalent (M-84) I’m gonna have to very strongly disagree on the “minimal ergonomic different” between the two tanks. It’s hard to quantify but 10% seems very generous to the Soviet designs. I assume I’m outside the 50th percentile for a Soviet man at the time the T-72 was designed but the ease of doing a lot of gunnery tasks in even earlier M1s and Leopards compared to the T-72 is night and day.

As I watched this, I was reminded of a video The Chieftain put out a while back where he was addressing the size discrepancy between Western (US, specifically the M60) and Soviet tanks. IF MEMORY SERVES, he indicated that the Soviet tanks were built for an offensive philosophy so they were smaller and crews weren't expected to 'live' in them for days at a time. Western tanks, OTOH, were expected to sit in defensive positions for extended periods, so were larger in order for crews to stay in them for days with some semblance of comfort.

"50th percentile" is an extremely low target. A more typical design target to suit 'most' people without excessive cost is fitting up to the 70th or 80th percentile (pending on what you actually design and how hard it will limit people). Designing a tank around the 50th percentile in body size will definitely make it extremely unergonomic for a large part of the population. Accomodating smaller people is often doable through adjustable chairs and instruments, but it sets a pretty hard limit on how effective taller people will be.

I would say, on average, the Russian tends to be shorter than the Ukrainian (ethnically speaking, not citizenship -- though that might be because Russians are more Asian, I don't know), and working-class people have a lot more surprisingly short individuals than the rich in the young generation, I guess the effects of uneven poverty and malnutrition in the 1990s-2000s.

On the British Chieftain and I guess Challenger 1 ( it had the same gun kit ) you would laze the target, track it for around 2 seconds and then press autolay. That would track the target but best to fire asap as tracking goes out the longer you leave it because the target won't hold a constant speed. For static targets you laze then autolay, the elipse that is displayed in your site will move to cover the target and then you fire with the command "firing now" pulling the trigger on the W of now so your commander and get his face away from the sight. For gunnery and D&M training ( Driving and maintenance training ) you would do it in the classroom and practically by actually doing it in the British army, when you got to your regiment you would learn a few "better ways" to do a few jobs but you would also get a lot more experience in actually doing it in the field while on exercise. It's not exactly the same in the field as in the classroom or on the tank park, that experience is what makes a good tankie who can maintain his tank in the field and reduce breakdowns. Unreliable Cheiftains were the early ones ( from what I heard they were really quite bad ) or poorly maintained tanks later on ( I only had one pack lift in 4 years on Cheiftain and that was down to a gunner driving my tank while I did my first range period, I was screaming down the intercom trying to tell him how to drive it properly while engaging targets. He labored the engine in too high a gear for too long and on the next exercise while I was driving it gave up the ghost. That was a damn good engine too.

When talking ergonomics there is imo one more thing to consider that was not mentioned here at all. And that is the amount of crewmen. Western tanks usually have 4, soviet tanks usually 3. Thats one less person to do maintenance, to stand guard etc. Its not a big deal for a short operation, but it multiplies the longer you are living in the tank.

a ukrainian channel called Shawshank redemption on youtube made a great video showing and explaining a captured russian t-72v3 and t-90a, it's incredible how little room they have, and because of a very compact design it lacks ANY sort of room for future upgrades, the scopes are bolted one on top of another instead of replacing them, which reduces the real estate of the crew even further

Well if you drastically truncate the training due to time constraints, you should expect the level of training to be less comprehensive.

[@jamesharding3459]

Having had the chance to sit in the commander’s and gunner’s stations on a T-72, I have to agree with the general thesis. It’s definitely not designed to be comfortable for a relatively tall person like me, but unlike a BMP-1 it wasn’t uncomfortable. All the controls (at least the ones I could read, my Russian is not especially good) were well laid out and readily accessible. If I were a Russian TC or gunner and actually trained on that particular track, I have no doubt I could effectively fight the tank. And also unlike aforementioned BMP-1, I think I could actually survive it driving over a small bump without losing several teeth or getting a third concussion. Overall, well thought out and a good design. If not for the lack of an independent thermal for the commander, it would definitely be on par with any other mainline MBT. Mind you, I would never trade my usual mount for a T-72, but that’s mostly because I’ve gotten used to having enough leg- and headroom to move get comfortable and enough space to shove a week’s worth of snacks and energy drinks into various crevices. The CITV and Blue Force tracker are nice, but the latter isn’t strictly necessary except for platoon or company commanders/XO’s vehicles.

@@mananaVestaRespectfully, there are areas that Ukrainians would be able to reach us in. Drone warfare and such, but then there are others that they shouldn’t try. Combined Arms warfare is one. Constantly and consistently we’ve seen them send out their tanks alone with no infantry support. That is a good way to get taken out by an ATGM, a Drone or a some guy with an RPG-29. Helicopter and Fixed Wing Aircraft is another, as they really haven’t been engaging that many Russian aircraft with their own just due to limitations of the available assets. While we haven’t been actively fighting LSCO since 1991, we still train for it, and have taken lessons learned from Chechnya, Georgia and even Pre and Post 2022 Ukraine.

@@andrewdenzov3303 Do you think NATO 'controls the intensity' because they don't want to win? No, it is a combination of lack of resources and fear of open war against Russia with its superior strategic and standoff weapons. But this war was never supposed to be fought out - Russia was supposed to collapse under the sanctions and the confiscation of its foreign reserves. Now that it is fought out NATO is out of ideas and just fumbling along from day to day, with no way to win and no way out (unless the Western leaders admit being totally wrong about everything and doing a 180° turn, which has a snowball's chance in hell of ever happening).

Combined arms is very good. On paper. How you could implement it when even couple of soldiers or MG nest is a valuable target for 155 mm? You had to gather forces far away from reach of rece drones and striking distance of 155 and MRLS. Than you had to get combat groups to enemy line under constant fire of artillery and drones.

My issues with 50th percentile design: 1. If both sexes will use something, their statistics are often bimodally distributed, meaning the majority of one sex is too large and the majority of the other sex is too small, with nobody actually fitting the design correctly. 2. Even if we can assume that the distribution is monomodal, there is often greatly asymmetrical effects from being too large or too small. Being too large is usually much worse if space is a premium, since you simply won't fit in a normal position, although being smaller can have its disadvantages as well, especially if the controls take a lot of strength to use. I would suggest the better option is to take your percentiles and integrate how effectively they could use the thing, possibly with a weighting exponent based on opportunity costs of how effectively they could use something else instead, them try to maximize the area under this curve.

Two other KZbin channels have come across it, so is it a T-72 thing?... With the T-72 why would a part from one country where the T-72 was built not fit onto a T-72 tank from another country? IE you can not mix and match parts of apparently the same design of tank with other partners that made up the Soviet block/Warsaw Pact?

[@CowCommando]

Could be a quality control issue. My Grandpa told me story about a project for the government he was part of shortly after WW2. The people in charge decided to swap some parts manufacturing to a factory in Mexico instead of the US to save on cost. The factory in Mexico was given the same blueprints and specs as the American factory, but some of the parts from the factory in Mexico wouldn't fit when the scientists tried to install them. They threw away so many out of tolerance parts that they lost money despite the cheaper cost. They went back to ordering from the US factory afterward and the problem went away.

[@dj1NM3]

There is a slim, small possibility that it a was a "monkey model" export version control that the USSR implemented, so that if there was breakaway nation, that they couldn't loot disabled Soviet tanks for spares when the Red Army rolled in to quell the revolt. Giving each satellite state a slightly different set of blueprints and specs, each would work as a system on their own, but wouldn't quite be compatible with each other. More likely it was just crappy quality control and lots of hand fettling to get things to fit and (mostly) function.

[@PeterMuskrat6968]

Different factories making things with varying qualities with different methods. Factory A in East Germany makes a part that is 1mm off from the blueprint, Factory B in Poland gets it almost spot on with just a 0.1mm difference. Part A will not fit into the same place as part B.

So I have been in a pt91, a t72m1, all m1 family vehicles, leclerc (while I was in kuwait) and a challenger 2. The t72/pt91 is the worse for the crew to function and fight in. The gunner having one fire button for the main gun and the other for the coax means that you could be in a situation where u need to keep u hand on the leftover handle but need to us your control switches or button on the left side. Meaning u would need to cross ur hands. That 1. Then the lack of guards/cage inside the turret means ur limbs can be lost. I am short 5'4 and yet my legs could be chopped off. That 2. 3rd. The lack of a heater. That was one of the 1st things both the cz and polish soldiers notice a huge difference between their tanks and m1a1 and leopards. 4th things on a tank. Auto loader goes down it hard to load a t72. 5th boresight a t72 family of tanks is really non exist. I used the mbd, string and used a mean with a mbd. The t72 method is not effective or good. 6th. Crew size. 3 crews means u pull longer guard duty on the tank. It also means if u lose 1 person u r down to two. For operation, guard, and maintenance. Greatly reducing the effectiveness of the tank. Stabiztion is not on all the time in t72. Crews can turn them on when they need them. Ppl forget. Most western tanks have them on whenever the tank is powered on and hydro. So ppl can't forget and u always have it. Sometime u are surprised and t72 crews will forget to turn it on. As a tanker with 22 years of army experience and another 5 years as a tank instructor. A lot of easy things are lacking on a t72. Remember we should judge tanks by it least experience soldiers using them. Not experts. As most will never be experts. I forgot about l the lack of redundancy on the t72 family of tanks. Again things break.

actually, having all controls "right in front of you" as a gunner is a bad layout. Your eye is on the sights, so things are better if they are to the sides of you. But what does a guy who was a BFV gunner for 3 years know?

Onhand, Offhand and Natural Ergonomics Very important Concepts

[@tankolad]

Not literally right in front, the most frequently used controls on the T-72's gunner's station were all on the control handles and the switch for the autoloader was right above his left thumb, so there was no need to break away from the eyepiece ever in an engagement. When fighting in degraded mode the wheel to operate the optical rangefinder could be turned with his thumbs. The most frequently used items were placed closer and to a more visible location. Infrequently used items like the fusebox (turning on/off the turret electrics) were stuffed into a corner behind the night sight.
