Basic Underwater Demolitions/SEAL (BUD/S)
Upon arrival at Naval Special Warfare Command, check-ins for BUD/S are immediately placed into a pre-indoctrination phase of training known as 'PTRR', or Physical Training Rehabilitation and Remediation. PTRR is also where all of the 'roll-backs' are placed while waiting to be put into a class. Once additional medical screening is given, and after enough BUD/S candidates arrive for the same class, organized physical training begins.

BUD/S consists of a three-week 'Indoctrination Course', known as INDOC, followed by three phases, covering physical conditioning (seven weeks), diving (eight weeks), and land warfare (nine weeks) respectively. Officer and enlisted personnel go through the same training program. It is designed to develop and test their stamina, leadership, and ability to work as a team.
