I too went to meps just recently for a physical(this time last year), they do have a guy watching you piss but they also draw blood, now, im not sure which is for what but if Im right I think the blood test is to make sure you dont have AIDS or any other disease and the piss test is for drugs and other bs.....not sure but ive experienced it first hand and just wanted to share my insight(I got out before they could trap me) FUCK BUSH! I wont go fight to make his pockets fat, ITS AN OIL WAR!
