If you non vet guys went through the training I did in 1967 you would understand. Discipline is drummed into your head from day one when I was in, if you acted up the Drill instructor might (would) kick your a$$ big time. This type of controlled environment didn't allow for the dumb stuff people do outside the military when they are drinking.
If you were a real bone head that affected the company's mission, there was a good chance you would get a blanket party held in your honor by your peers. For those who don't know what a blanket party is; The guilty party is approached from the rear, a GI wool blanket is thrown over his head, he is caught by surprise and is pummeled by all the folk that decided he needed an attitude adjustment.
We had one guy in basic who's personal hygiene was abysmal, he didn't even use toilet paper. We got sick of his nasty ways and put a bar of yellow lye soap and a stiff scrub brush we used for the concrete floor on his bunk. We told him if he didn't clean up his act we were going to hold him down in the shower and scrub every inch of his nasty body with the lye soap and the scrub brush.
He instantly became very focused on his cleanliness.
Like I said guys, the military is a different world and can't be compared to the world non military people live in .
