Read the fine print. Training opportunities differ, but your initial enlistment contract will outline everything you're entitled to and guaranteed.
Second, think about what you want to do post-military and ask yourself if the training and job experience the recruiter is selling you will put you on track to do that.
Lastly, if you want a job, go Air Force or Navy. If you want to join a fraternity in arms, join the Army or Marines.
P.S. OP, if you have any other questions, feel free to send PM.
