Man I feel sorry for the Officers in BUDS. They expect perfection out of every single person in BUDS, they expect more than perfection out of the Officers. From what I've seen of it and the SEALs that I've operated with, BUDS is absolute hell on Earth. You have my utmost respect for even attempting such insanity!

P.S - I don't know your disposition and I'm not 100% on the details but see if it is possible for you to get a Corpsman guaranteed SEAL contract. My old corpsman was a SEAL contract enlistee but I don't know exactly how it works. The reason I say this is that if you fail out of BUDS (And realize now that failing is a probability!) you will still be able to go 'Green side' and operate with the good ole' USMC. The SEALs we ain't, but operating with us (And the opportunity to get on our Recon teams) will probably beat the hell out of being at the whim of the Navy and ending up behind a desk.

***DISCLAIMER*** Not that being behind a desk is a bad thing or makes your service any less important than anyone else in the military but if you are wanting to be a SEAL you are probably of the midset that you want to shoot things, blow stuff up, see some combat, and generally partake in other non-sane activities.
