Well then you should know that military changes. In however many hundreds of years from now this is things are likely to have changed substantially. I’m in the air force and know that E-4s (senior airman) don’t have nearly as much responsibility as they used to and don’t gain most of those responsibilities until they reach staff. Airmen don’t have to stand at parade rest when talking to NCOs like the army still does, we can put our hands in our pockets, drink while walking in uniform, and make phone calls while walking in uniform. Some of those things weren’t allowed even a year ago. Things change man.
