BUD/S Basic Underwater Demolition/Seal - This is the training program that all members of underwater demolition and seal teams undergo. UDT-14 is Underwater Demolition Team 14 (It was redesignated as SEAL TEAM 5). The UDT teams were the foundation of the Navy Seal TEAMS. All members of Seal Teams went through BUD/S and some individuals were assigned at different times to both Seal and UDT units.
The person I was reffering to I served with in UDT fourteen.

As far as BUD/S goes, I heard from an active SEAL something to the effect that BUD/S makes Basic training look like kindergarten...
