I've started to look into going back into the service after I graduate college in about 2 years. I spent 6 years in the Navy as a submariner, but am now looking at one of the ground branches (Army or Marines). I've actually talked to the Marines, the Lt. I talked to seemed interested and thought I'd make a good candidate for OCS. My question is, what do Marine Corps or Army junior officers do on a day to day basis? I know what they do in the Navy, but the other branches are a mystery. I want to know what goes on in an average days work. Wanna kill these ads? We can help!
