1 Assault Group Royal Marines (1AGRM) are Britain’s premier experts on Amphibious Warfare. The group comprises of the Headquarters in Plymouth, 10 Landing Craft Training Squadron in Poole, 11 Amphibious trials and training in Instow and the Royal Navy School of Board and Search, HMS Raleigh. The organisation is tasked with training and parenting the Assault Squadrons of the Royal Marines (ASRM) and their Landing Craft detachments. These ASRM provide the Landing Craft and fighting capability for the Royal Navy’s Amphibious Capital Ships (HMS Ocean, the Albion class Landing Platform Dock) and 539 Assault Squadron Royal Marines, the organic ASRM within 3 Commando Brigade RM. As part of the Devonport Landing Craft co-location project, the 1AGRM HQ element moved from Poole to Devonport, Plymouth in December 2008, with 10 Landing Craft Training Squadron expected to follow in approximately four years time.
