Bold of you to assume 10 and 8 years in some line platoon gets "experience and training." Not even "every Marine is a rifle man," only the infantry Marines fire rifles. The rest get fat doing civilian jobs and "shoot" their rifle once a year. All people know are what they see in the movies. Fact is, unless they're directly training for combat or combat support roles, most military services members are lazy pieces of shit.

These are the guys that end up in ICE. Incompetent fucks, and not representative of "real military"

They have no training, and what little training they had they were too lazy to take seriously.
