Sergeant Jeffrey O. Burton, a 25-year-old avionics non-commissioned officer in charge for Marine Light Attack Squadron 369, currently attached to Marine Medium Tiltrotor Squadron 265 (Reinforced), 31st Marine Expeditionary Unit, and a native of Goose Creek, S.C., works on the tail of a UH-1Y Venom helicopter during maintenance here, Sept. 3. The helicopters are supporting the battalion-sized element currently conducting Exercise Koolendong 13. Koolendong demonstrates the operational reach of the 31st MEU and reinforces why it is the force of choice for the Asia-Pacific region. Also participating in the exercise is the Marine Rotational Force – Darwin and soldiers of the 5th Royal Australian Army. The 31st MEU brings what it needs to sustain itself to accomplish the mission or to pave the way for follow-on forces.
