SeaBee Slog.

Ensign Frank Sysko, assigned to Naval Mobile Construction Battalion (NMCB) 3, exits a mud-filled trench during a jungle warfare training session at the Marine Corps Jungle Warfare Training Center (JWTC) in Okinawa, Japan.

The JWTC endurance course tests the Seabees will, stamina and the ability to work together as a team. A total of 49 Seabees from NMCB 3 attended the five-day course.

NMCB 3 deploys to several countries in the Pacific area for construction operations and humanitarian assistance projects.
