USMC POOLEE couple questions before i ship. please help?

Starting with ur MOS.. there is a chance you may get to go overseas to do ur job, but if u really wanna change ur job you can do it after ur second yr in the Marine Corps. well my best friend is a poolee and i am a future poolee. and he wears nothing but marine t-shirts. it is not offensive. it shows you are proud of what ur are going to become, and it supports the Marine Corps. just dont say ur a Mairne become one, dont wear shrits that say ur a marine wear shirts that support the Corps.
