After eliminating their entire unit, the Royal Marines “dominated” US forces days after they began a training exercise. 

American combatants asked for a ‘reset’ halfway through a five-day simulated war exercise at the US Marine Corps’ Twentynine Palms base in the Mojave Desert in southern California, having taken significant casualties from British commandos using a new battle structure, The Telegraph reports. 

The Marines’ kill board’, which evaluates damage done to enemy assets, had one tick against nearly all American assets. It meant that it had been rendered inoperable, or destroyed.  

British forces were trialling the new Littoral Response Group (LRG) structure, which will be the new template for commandos – who are to become more flexible and mobile under reforms directed by First Sea Lord, Admiral Sir Tony Radakin.

Following the restructuring of the Marines, Nato's northern and Baltic flanks will be covered by the UK-based LRG (North). LRG (South), built around Taunton-based 40 Commando, will be based afloat around Oman's port of Duqm, operating with a focus on British military activity in the Indo-Pacific. Each LRG will be capable of working with the carrier strike group to assemble an expeditionary strike force which can operate anywhere in the world
