The BvS10 (Bandvagn Skyddad 10, also known as Bandvagn 410 or BV410) is a tracked articulated amphibious all-terrain armoured vehicle produced by BAE Systems Land Systems Hägglunds of Sweden and by FNSS of Turkey (under license). 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.

The BvS10 is similar to, but distinct from, Hägglunds earlier Bandvagn 206 or Bv 206S. It is a much larger vehicle based upon the characteristic twin-cab, articulated frame-steering system typical of Hägglunds all-terrain vehicles. The main differences from the older Bv206s are a more powerful Cummins 5.9 litre diesel engine, improved ground clearance, and newly developed chassis, power train and steering units that give the vehicle considerably enhanced speed (up to 65 km/h from the previous 51.5 km/h on road) and comfort on road and in terrain, as well as greater load-carrying capability (up to 5 tons), and the ability to add various modular sub-systems such as add-on armour, weapon mounts, a load-changer and cargo platforms.

Originally designed for the British Royal Marines and named Viking, the vehicle underwent extensive trials and development programme from 2001 to 2004, led by Major Jez Hermer, before the Royal Marines accepted 108 vehicles into service, with delivery commencing in 2005. The Royal Marines Armoured Support Company took the vehicle on operations for the first time in Afghanistan in September 2006, prior to the Royal Marines Armoured Support Group being formed in December 2007.

The UK currently operates four variants of the vehicle : The Troop Carrying Variant (TCV) capable of carrying 2 crew plus 10 passengers; the Command Variant (CV), which carries 2 crew plus up to 8 passengers with the rear cab being designed as an enhanced digital communications platform, the Repair and Recovery Variant (RRV), carrying 4 specialist maintenance vehicle mechanic crewmen and the Ambulance Variant (AV). The rear cab of the RRV carries a HIAB crane, a fully mobile workshop, an air compressor and a 9 tonne capacity capstan winch, together with hydraulic anchors. All four variants are fully air-portable under a Boeing CH-47 Chinook helicopter, either complete or in two separate front and rear component parts and are also fully amphibious; being capable of swimming in varying sea-states with a full load of passengers and stores.^{[citation needed]}

UK Viking vehicle variants are used as amphibious armoured all-terrain vehicles for troop transport and as vehicle repair recovery vehicles.

Some 33 British Vikings, fitted with slat armour, were deployed to Afghanistan at the end of summer 2006 when the Royal Marines relieved the Parachute Regiment in Helmand province. Their low ground pressure is not enough to trigger most of the anti-tank mines in use in Afghanistan, but they have proved vulnerable to improvised explosive devices (IEDs). Viking was subsequently upgraded with higher levels of Armour protection. Vikings were replaced with the ST Engineering Land Systems (STK) BRONCO known as Warthog within the UK military.

In May 2007 the Ministry of Defence placed an order with BAE Systems Hägglunds for a further 21 units, some of which are to be used as an equipment transporter for the new Thales Watchkeeper unmanned aerial vehicle.

Additionally on 26 June 2008 the MoD announced the purchase of an additional 14 Viking BvS10 vehicles at a cost of £14 million, including nine repair recovery vehicles, one command vehicle and four troop carriers, for deployment to Afghanistan. In January 2009, nine more vehicles were ordered.^{[citation needed]}
