Smile, wait for flash
A student from Tactical Bow Gunner Course (TBGC) fires blank ammunition at a target vessel during a simulated non-compliant scenario at Camp LeJeune, NC. TBGC is designed to train tactical bow gunners for Ports, Waterways, and Coastal Security (PWCS) missions.
The TBGC is a five-day course s for enlisted members E-7 and below designed to train tactical bow gunners for PWCS missions. They get schooled on the M240B, the LA51 Warning Device and the M-870 Remington shotgun (a nice SBS with a 14-inch barrel) as well as security zones; command and control; crew member equipment; and response boat tactics.
The LA51 is a sweet little shotgun-fired flash-bang that is guaranteed to get your attention.
