So your saying the army? Because they have army, navy, air force, marine corps, coast guard, and national guard. I'd prefer medical field if possible. I'm not best shape of my life but I'm not bad (can't do 20 pushups, cant run a mile ect ect but I'm not bad lol). I'm 18 turning 19 this year. I'm about 5'10 and about 185 pounds.
