Lance Cpl. Chase J. Dusenbury, an 18-year-old motor transportation mechanic for Combat Logistics Battalion 31, 31st Marine Expeditionary Unit, and a native of Lexington, S.C., removes attachments from the engine of a High Mobility, Multi-Purpose Wheeled Vehicle here, Sept. 1. The Marines of CLB-31’s maintenance section are working long days and late nights to keep pace with the required maintenance that comes with supporting the battalion-sized element currently executing Exercise Koolendong 13. Koolendong is a week-long, live-fire exercise that 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. The size and composition of the 31st MEU makes it well suited for amphibious operations, which includes raids, assaults, evacuations and humanitarian assistance operations.
