In November 1998 PSU TRADET relocated to Marine Corps Base Camp Lejeune, North Carolina and by the summer of 2001 its mission had expanded to include non-lethal weapons and the Fast Boat Center of Excellence, as well as conducting training for cutter small boats over-the-horizon tactics designed to enhance interdiction abilities in counter narcotics operations.

After the terrorist attacks of 11 September 2001, the PSU TRADET began training the newly created Coast Guard Maritime Safety and Security Teams (MSSTs).

In 2006, the NAVDET and MARDET commenced a two-year training surge for the Navy's new Naval Expeditionary Combat Command (NECC) Riverine Forces.

All Coast Guardsmen who have been selected to serve in the Middle East in support of Patrol Forces Southwest Asia and Operation Inherent Resolve also attend pre-deployment training at SMTC.

Training includes various service small arms, such as the M240B, M2 Browning machine gun and the Mk 19 grenade launcher crew-served weapons system.

Procurement and contracting are done through various sources including those used by Marine Corps Base Camp Lejeune as well as UNICOR, General Services Administration and commercial vendors.
