Sgt. Brett Oros, a food service specialist with Marine Wing Support Squadron 373 based out of Marine Corps Air Station Miramar and a Wallingford, Conn., native, braces himself as a wave builds itself to crash into him while he wades through the surf of Fort Hase beach aboard Marine Corps Base Hawaii during Sergeants Course Aug. 19, 2015. Oros, along with the other sergeants in the course, participated in a scenario where they were outnumbered 4 to 1, and needed to repair a broken down vehicle. Sergeants Course is a vital part of professional military education for any Marine and helps to maintain the standards amongst the NCOs of the Marine Corps. The course supports MCB Hawaii’s mission, which is to provide facilities, programs and services in direct support of units, individuals and families to enhance and sustain combat readiness for all operating forces and tenant organizations aboard the installation.
