The elite troops of the Royal Marines Armoured support group are getting ready to go to war in this amphibious assault transport. The vehicles are meant to be a key part of the Royal Marines rapid-reaction capabilities. The Royal Marines ordered Viking vehicles as part of the Commando 21 reorganization. The Viking All-Terrain Vehicle was meant to provide armoured, amphibious mobility to the Commando groups. The Viking proved extremely useful as a tracked vehicle capable of negotiating the ditches, canals and uneven ground. The BvS10 vehicle development was based on the operationally proven capability of the Swedish Hagglunds Bv206 and Bv206S vehicles. Over 11,000 vehicles are in service in 40 countries.
