Maj. Jeramy Green, assigned to the Command Element of the 31st Marine Expeditionary Unit aboard the amphibious assault ship USS Essex, searches through a bag of donated shoes for a young Cambodian boy. Essex and the embarked 31st Marine Expeditionary Unit are in Sihanoukville, Kingdom of Cambodia, for a scheduled port visit that gives Sailors and Marines the opportunity to participate in friendship-building community relations events, medical and dental projects and professional exchanges. Essex is the lead ship of the only forward-deployed U.S. Expeditionary Strike Group and serves as the flagship for Combined Task Force 76, the Navy's only forward-deployed amphibious force commander. CTF 76 is headquartered at White Beach Naval Facility, Okinawa, Japan, with a detachment in Sasebo, Japan.
