Anyway, size is not something that is desired at all. And, at least in the United States, the US military is a relative reflection of the population at large. You get all sorts of sizes of people, but more often than not your average height is going to mirror the average height of the population. Most of the guys in the Marine Corps were roughly between 5'9" and 6'1", give or take an inch here and there. By no means were the biggest, strongest guys the best performers either. For instance, the machine gun section leader in my company was incredibly strong. He could bench over 500 lbs. But he had back problems and the few times he went out on patrol with us it was problematic for him on some occasions. The biggest reason is because, while weight training is effective way to increase strength, there is not a direct correlation to how you perform when you are loaded down with all the equipment, ammo, water etc and asked to go walk for hours on end in bad terrain, in the heat, and all of that. You need a strong back for this stuff, but not everyone focuses their weight training on their back muscles. Likewise powerful traps help offset the immense pain you feel in your traps when you're operating, because a significant amount of weight is focused on that part of your body.
The most important aspect is endurance. Both physical and mental. Sure, you do lots of long distance running, crunches, pull ups, etc, but I've seen many people that perform just around average levels in these events excel when you load them full of weight. I certainly never did the most pull ups, nor did I have the fastest three mile run time. In fact my run times were generally pretty average-- around 23-24 minutes. But most of the guys that could do it in 18 mins usually got smoke checked when you through all the gear on them and told them to run range 400. Endurance is key. And just being able to stomach the consistent, irritating pain that is basically starts 10 minutes after you've left the wire and only gets worse as the seconds tick by. If you look at most professional troops they are not built like body builders. They are more lean and sinewy and while the muscles may not be big, and they may not power lift a metric ton, they are strong enough to perform the tasks required of them repeatedly. That's the most important aspect. I had a Tongan in my fire team who was just stacked muscle on muscle. I once saw him benching. He had 315 on which wasn't too insane, except that he was playing with it like it was nothing. Yet when we geared up and went out he often struggled because he didn't have the proper endurance. He usually suffered more on patrol than my more wiry guy that had a background in baseball. He wasn't nearly as strong as the Tongan, but he could hump a lot of weight for a long time.
Nevertheless, in the units I served in during deployment, weight lifting was a major pass time and so everyone became much, much stronger. As an example, I maxed out my bench press in Afghanistan at 265 lbs. I was all proud of myself, but actually I was pretty average. Most guys were doing over 300 pounds. And the peculiar thing about your environment and the patrolling means you're not putting on excessive weight normally associated with bulking. In the States when I lift heavy I'm typically 190 lbs give or take four or five pounds. In Afghan/Iraq I was usually hovering around 170-175 lbs. I'm 5'9", most guys were about my height.
On another note we had guy in my battalion that was like 6'8" or some such and he was absolutely considered a liability. First, he was not even allowed to go on the MEU because he was too big for ship life. Second, when we went to Afghanistan he actually had to sign a waiver saying he was opening himself to more risk because of his size-- principally because he may not have fit in a Huey if he needed to be MEDEVACed and the closest bird was a gunship. Carrying an average size male that is wounded is already a horribly difficult experience. Doing it with someone that size is almost impossible. Not to mention all the problems he had finding cover. I remember observing for his squad on a company attack and following them through some defilade they used to get closer to an objective. All the other Marines were well covered in the dry creek that we moved through except him. He towered above everyone else and, if there was an enemy, they'd have seen him and opened fire long before we were in our final assault position. Even though he was crouched over the entire way. He was simply too f'ing tall.
