For the DD368, we prefer that the expiration date of the 368 (Conditional Release) be far enough out to extend past your enlisted date just prior to shipping to OCS. This is because the 368 represents your conditional release from your current military obligation up to the point in which you fall under a new military obligation with the other branch of service or service component. So if you are concerned about the expiration date on your 368 coming up soon, and perhaps expiring during your selection board or shortly after, I would recommend that you ask your current branch to consider extending the 368 or generating a new 368 that reaches out in the future a little further so that you wont end up perhaps having to scramble around to get one at the last minute because it expires 1 week before your enlistment date right before shipping to OCS.
