The current Royal Marines Armoured Support Group (RMASG) is an element of the Royal Marines that operates the Viking BvS 10 All Terrain Vehicle. It is based at Bovington in Dorset. The original RMASG was formed in the Second World War to give British and Commonwealth forces heavy fire support in the opening attacks of the Normandy landings.

The BvS10 is a tracked articulated amphibious all-terrain armoured vehicle produced by BAE Systems Land Systems Hägglunds of Sweden. This vehicle, referred to as the All Terrain Vehicle (protected) - ATV(P) or Viking by the UK forces, was originally developed as a collaboration between industry - Hägglunds Vehicle AB - and the British Ministry of Defence (MoD) on behalf of the Royal Marines.
