My girlfriends little brother just signed his papers for the army 2 days ago. He just found out today that he is being sent to Missouri on the 25th of this month. Is it normal to be sent off that quickly after signing papers? Hes doing Airborne Artillery btw. Also, what exactly is Airborne Artillery? Im guessing its it has to do with jumping out of planes with guns? And what is the ratio of Marines to Army when getting sent out to war zones? The last two questions her family are really worried about, because naturally the first thing for the uneducated is to assume is your son is being shipped out to Iraq.
