Backintheday when I was in the military one would learn a few things early on...
Fresh Haircuts
Clean uniforms
Footwear kept in good condition
Keep you muzzle pointed down range
Keep your mouth shut and your ears open
Don’t talk about politics, sex, or religion.
Don’t wear your heart on your sleeve.
Bumperstick protocol, even underwear restrictions - which came later when some female admiral in some female lockeroom got an eyefull... One can only imagine.
as an army brat, i learned these words of wisdom also. i didnt always listen though..
