I need to get my class A's for my EM residency interview at the end of September- I'm Air Force HPSP. I was commissioned just before my third year and have not yet attended COT, as it has interfered with my 3rd year/4th year schedule and I have received a deferment. I therefore do not yet have a uniform and have no clue as what I need for my uniform. I am going to a Military Clothing Sales Store next week to get hooked up. Can I rely on the sales associate to purchase all the "necessaries" or can anyone give me some info on what additionals I will need to purchase? Any help will be much appreciated.
