Whatever you do get everything in writing. Do not believe a recruiter. They lie. If they promise you something. Get it in Writing. Read you contract carefully.
I can verify that. One of my jobs in Army Personnel at one point was dealing with soldiers who had made complaints, often to their Member of Congress, about false representations at the time of enlistment.
If it isn't in the contract, it don't exist, period. Recruiters are under enormous pressure to make quota, and some will bend the rules, to put it politely.
A recruiter must provide you, in a written contract form, all enlistment incentives (money & civilian educational benefits) you will be getting, all military training you will be receiving for your agreed upon career field, and the precise date of your separation from active duty.
(A period of Reserve Duty will follow Active Duty for a grand total of 8 years on an initial enlistment. "Stop Loss" provisions may be legally implemented to involuntarily extend your original Active Duty commitment up to the full 8 years, as has already been done by the Bush Administration to support the Iraq War)
