I don't want to be a naysayer but it deserves saying: make sure you want to be in the Navy, not just a SEAL. An awful lot of people don't make it through BUDS and if you don't....be prepared to swab decks. You can be the badest ass of them all, but if your knees/shins/whatever blow up, you're still in the Navy. You can be physically qualifed to remain in the Navy without being BUDS qualified. Plan A is great, but make sure there's a plan B you can live with.
