USS PELELIU (April 26, 2013) Sergeant Adrian N. Edeyaoch, squad leader, Security Platoon, Maritime Raid Force, 15th Marine Expeditionary Unit, practices calling for fire using the Digital Virtual Training Environment during a modified joint fires observer class on USS Peleliu, April 26. Calling for fire or calling in a casualty evacuation are tasks normally associated with scout observers or joint terminal attack controllers. These Marines, many in the ground occupational field, specialize in controlling aircraft. The scout observers with the Command Element, 15th MEU, held a class to help prepare the MRF for the variety of missions that scout observers typically conduct such as controlling aircraft for air strikes or requesting casualty evacuations. The 15th MEU is deployed as part of the Peleliu Amphibious Ready Group and is comprised of approximately 2,400 Marines and sailors. Together with Amphibious Squadron Three, they provide a forward-deployed, flexible sea-based Marine Air Ground Task Force capable of conducting a wide variety of operations ranging from humanitarian aid to combat. Edeyaoch, 25, is from Koror, Palau. (U.S. Marine Corps photo by Cpl. John Robbart III/Released)
