What's more interesting is that this is not always known to people inside the group; that they believe it to be the standard (people from other military occupations are likewise often surprised when they witness a group of people team-chanting about killing people, having believed their own approach to be standard, and in my experience some European military find it a little disturbing, as they tend to be even further removed from this approach). Everyone takes their own experience and generalises it across the board; the US marines are an extremum in the field of mentally preparing (or indoctrinating) people to kill.
Horses for courses; it only becomes a problem in the field when you put people heavily indoctrinated in killing into a deployment where not shooting people is really what's needed, and vice-versa. Unfortunately, that's where it has fallen down over the last decade or so.
Yes, I was in the U.S. military 25 years ago. I will leave it at that and not try to demean your opinions with an unnecessary personal attack. It's just the Internet, after all, and 'winning' an Internet argument ain't worth it ;-).
The Marines literally make you say "kill" during combat training.
The phrase for firing a machine gun is "die mother fucker die mother fucker die mother fucker release" (release the trigger to prevent over heating of the barrel)
Every time we went on a platoon run the diddies are about murdering our enemies.
I honestly don't believe you were in the military, or you seem to have forgotten what it was really like. Or maybe you were in the air Force, but definitely not the Marine corps.
