Because your position is infantile. You don't understand what we do at the most basic level. Protecting waterways, protecting air traffic, counterpiracy, humanitarian missions, you have no fucking idea and to even try to equate us to something like ISIS is so ignorant I don't have words. You have NO idea what we do. I personally have helped for Sri Lankan tsunami relief, helped deliver food and tents to pakistani earthquake victims, protected villages, helped run electricity to remote iraqi villages, and that is just the shit I have done, at my few commands. You don't know what a military does-it isn't all kicking in doors and dropping bombs, that is a small part of providing defense to our allies.
ANYWAYS. Back to uniforms for a bit, our aquaflage camo is to help hide grease and paint stains from working. It is in tones that hide that so you don't have to buy a new uniform after accidentally running into a fresh painted bulkhead or cleaning a .50 cal.
And yes, as far as unis go I have coveralls, 3 types of camo(aquaflage, desert, woodland), NSUs, dress whites and dress blues. It's ridiculous. On top of that I have to buy the new female dress blues and cover this year and if I make chief(E-7), I have to an entire new set of uniforms-_-
