Yeah, as often as Mommy and Mommy's Life Partner told you that you were the most special, precious, and unique snowflake of them all, once inside the machine, you're just grease for the gears. Quoth the Floyd, you're just another brick in the wall, and replaced just as easily.
That's why it's vital that you look out for your buds and your subordinate troops, and even yourself if that doesn't conflict with looking out after the first two. Beyond section level, no one really gives a shit about you unless you are fucking up in a spectacular fashion. Keep an eye on buddy, in the field, in the shacks, in the mess, and understand that if he is worth two shits, he'll be looking out for you too. In the shut up and die ranks, all you have most of the time are the two jackasses to your left and right. They may be assholes, but they are YOUR assholes, so you gotta love 'em like brothers. Brothers with Tourettes and homoerotic issues, but bros anyway.
