Is BUD/S pre navy seal training I believe I mentioned earlier on this thread some ROTC buddies not making it through BUD/S.
BUD/S is the training to be a member of the Teams. Hell week is one of the more unpleasent things that must be endured. The young gentlemen in ROTC may get the chance to try making it through BUD/S when they are fully in the armed forces. It used to be any member of the armed forces from any branch could volunteer to be Seal. I believe it is still that way. It is not primarily a physical challenge. The physical part almost anyone can accomplish the primary challenge is to stick it out (some say to be too dumb and stubborn to ring the bell). If you make it through BUD/S that knowledge can help you endure many other things.
Now I do not know if ROTC members (not graduates but students can go through BUD/S at present). It used to be only active duty personnel could go through the course but I have heard through the newletter about a Seal explorer scout program but since I am not near the San diego area I have not paid a great deal of attention to it.
