Sorry to say, but if you already signed the contract and enlisted as "Open Contract", then you're stuck with that. There will be no more discussions about picking MOS's. You'll be at the mercy of the needs of the Corps.
But on the flip side... I enlisted open contract and got put into an MOS that I love. Smalls Arms Repair. I get to play with guns all day.
not true. i signed originally under an open contract due to me join the dep in june of 02 and then once the next fiscal year rolled around i had first dibs on the jobs my recruiters got. once oct 1st 02 hit i signed for the mos i wanted. op i didn't read all the way through but if you are interested in mechanical, look into the airwing. i'm sure someone probably already said it but you can make really good money fixing aircraft after you leave the Corps. i'm a former 0311/8152 myself. gl :beer:
