As an essential part of their qualification process, all SEALs must attend a three month SEAL Tactical Training (STT) course at their gaining command where they further enhance their operational skills and field craft. Upon completion of STT, SEALs are assigned to an operational SEAL platoon or SDV task unit for their initial operational assignment.
