I excerpted a thread about this ten days ago: www.unz.com/isteve/why-the-infantryman-is-still-a-man/. Read on if you want some soldiers' perspectives.
"Most infantrymen lift, but that’s not the hard part. Civilians aren’t used to carrying those loads on their backs, there are all sorts of muscles and callouses you have to build and nerves you have to kill in your shoulders and feet to be able to do it. This is why Infantry units ruck march weekly. My first ruck in basic was only with a forty pound pack, rifle and water for five miles. One of the worst days of my life. Within a year, I was running twenty miles in full battle kit with an eighty pound ruck. In country, 120-150 lb was common, but we didn’t march nearly as far."
"In the long run it would help if we didn’t torture the guys with excessive training for long road marches that never happen in combat. We spent a shitload of time getting good at moving by foot with everything we had for days at a time over miles and miles of terrain. That’s fucking stupid. All you get out of that is a bunch of guys who have blown out knees and backs by the time they hit thirty.
We almost never moved miles and miles at a time with full rucks in combat, that’s why god created blackhawks.
What we did do was a lot of patrols with half of our battle rattle and you trained so that when someone got hit you could handle all of your gear and theirs at the same time.
Oh and I can tell you guys something else that nobody wants to hear about women in combat. The fact is that by the third deployment they are no longer up against regular men, they are up against guys who have taken roids for the injuries they have and to get ready for the next deployment fast enough.
It’s not enough to be able to get your body in condition enough to get through Ranger School or something like that. That’s a one off situation where you put everything you have into it and that’s it. Either you have enough or not. That’s not how it works in real life. In real life it’s like getting ready for the next season of football. Do we really think that women’s recovery time is going to be good enough? Fat chance, that’s why roids are a secret now. Nobody wanted to admit that even the MEN couldn’t get the job done without them, but it was true. Sure some of the guys could hang without using them but the fact that a lot of guys felt they honestly needed them to survive should tell you a whole lot.
I’m not saying women don’t belong in combat either. I just don’t see the point when it comes to straight up infantry units. Now if they want to put together sniper teams with women, I’d be all for that. Some of them bitches can shoot, I’ll tell you what!
Now aside from all the whoa whoah crap the best bet would be to stop this nonsense and worry about our own country for a change."
"I was a lot older (enlisted at aged 27) so was relieved to be able to ride in the Humvees. But, much to my chagrin, we still participated in a lot of humping (road marches). We always brought along the completed .50 cal system when we humped. For my unit, our basic combat load was 55lbs consisting mostly of our Alice/Molle packs, plus whatever weapon we were assigned (most issued M-16, squad leaders or gunners issued an M-9). Which by itself was a lot, but then you add in the .50 cal and it was a bit much. The receiver of the .50 cal weighs about 50lbs. The tripod was 44lbs and the barrel was 24lbs. We would distribute the system among each other. With one Marine starting out with the receiver, one with the tripod, and two Marines each with one barrel (spare). Put them up front and the rest of the Marines fell in behind them (we typically went on humps with two complete systems) and as they tired they would yell “Barrel Right!” or “Receiver Left!” and the next Marine in line would run up to them and take over carrying duties. We would do this the whole hump. So, depending on what piece you were carrying our weight was as low as 55lbs, then would jump to 79lbs with the barrel, 99 with the tripod and 105lbs when carrying the receiver. The tripod’s were later replaced with a better/lighter version. The barrel was fine to carry lighter weight and could sling across the pack quite comfortably, but the tripod and receiver were nasty.
The Marines value physical fitness. We had a lot of PFT studs who could kill it on the PFT test. I was fine with fitness always more athletic than strong. Always scored a first class PFT score (not that hard to do really and I got the old man discount). But in my platoon (and many other CAAT platoons) the real mark was what you carried on the humps. We “conditioned” up to 25 miles so we would do about 1-2 humps per month, culminating in the 25 miles hump. I never fell out. Always there at the end, never ignored the calls from my brothers when they could no longer carry their piece. The was the true test of toughness in my platoon. Not PFT scores, not book knowledge, but what you did on the humps.
We had some strong fellas. It was about the back and more importantly your heart. I only did 7 years in the Corps but it wore me down a bit. "
Why we use heavy infantry like this:
"Wikipedia gives a fair answer: https://en.wikipedia.org/wiki/Light_infantry
Roughly speaking, heavy infantry can destroy a lot more than light infantry, but (a) can’t go everywhere and (b) doesn’t have the infantry to search an area in detail. So, the opposition lives where (a) heavy infantry can’t go, because of its equipment, or (b) hide in inhabited areas where heavy infantry can’t search effectively enough to find them.
On the other hand, light infantry eats troops, both during and after combat. If we’re in an attrition war (as tactics indicate), why use light infantry? The answer to that has been obvious since the Port Arthur attack by Japanese forces in the early AD 1900s. Light infantry eats troops, don’t use light infantry in attrition wars. If you have an attrition war and you can’t stand attrition, you’ve lost. Make the best of it, try to win the peace negotiations, lose your table stakes, and rebuild. Don’t throw your society into the furnace. Simple as that, and as hard to face.
Disguising light infantry casualties by over-use of body armor, which produces joint injuries that aren’t attributed to actual combat, is an attempt to deceive the public, as is the “They serve so you won’t have to” advertising slogan of a few years ago was. “We have casualties, but they don’t count because . . .”. But they do. Each is a member of your society, as are that person’s relatives. You need them."
From the same commenter:
"As I’ve said in other posts, our side isn’t good at attrition warfare. That’s a consequence of having a K society, one that invests a lot in its members and relies on competent citizens. Each infantryman that dies means an important function not performed. Other societies have many completely non-functional citizens, crunches they can lose in war and never miss them. The West used to be like that as recently as the Napoleonic wars. People who could earn a living in society strongly tended to remain out of military service, and there was no legal conscription (barring press gangs and the like, small scale affairs mostly). Mass mobilization for WW I left participating societies without the people they needed to keep existing, and with considerable ill feeling from those people left sound after the conflict.
So, to paraphrase myself in a couple of other posts, don’t get into an arse kicking contest with a porcupine. If attrition is the only way you can win, then lose and save what you can. That or use area weapons and disintegrate the opponent’s society (that was the threat of the Cold War that prevented most attrition contests with Russia). Either is better than disintegrating your own society...
Or better yet, live in peace and fight wars only in video games. If possible."
A little more about body armor.
"Former infantryman here – answer is yes, they do lift, but in my experience the big lifting craze started after 2001 and all the deployments. Very likely had something to do with lugging all that armor around, but coincided with the crossfit / free-weight renaissance. The lifting is a good thing, but I’m less certain about the armor.
20 lbs doesn’t sound like much, but it matters when you’re trying to run, jump or dive. The ballistic plates especially really bounce up and down, seriously impacting the body’s natural motion. Add weapon and everything else (I was almost always carrying at least one radio in my one Iraq tour) and the struggle is real. It slows you down significantly. The experience gave me sympathy for breast-reduction patients. Also – and this isn’t much discussed – it affected my marksmanship. It’s just harder to tuck the stock into your shoulder and draw a sight picture with all that bulk.
If the conflict had involved lots of movement and close combat, maybe the armor wouldn’t have been worth it. In an environment where most casualties are caused by unexpected explosions and sniper fire, armor is probably worth it. But it’s miserable to wear."
"Current high coverage body armor was required by US Congress, not the Army, during the early stages of the current round of Middle Eastern warfare. Congress didn’t want large casualty numbers, and required more coverage than the Army wanted. Current loads minimize combat casualties, but cause joint injuries that manifest in later life — injuries Congress doesn’t much care about as they don’t affect the next election."
