i was in he army , m1 tanker , so i got to serve on the lines with the squishies (infantry, because they squish as you run them over) but i toked the whole time i was in execpt for basic of course. make and become good freinds with your drug and alchohol nco. he will be able to give you a heads up when ever your gonna have to take a piss test. also dont sweat the test at the meps station, i was hot for mine and they " lost custody of the sample" so i just had to take another.

if you want to stay out of combat go into postal or supply. tanks, infantry, artillary, engineers, medics, truck drivers, mechanics, recovery get to see combat.

if your lookin to travel and see some foreign country join the army or the airforce. they have bases all over the world. where as marine and navy just get to see the ports and dont always get off the ship

good luck and have some fun
