Here are the top 10 military traditions that need a lot of explaining to your civilian family members.
BAE's BvS 10 Amphibious Vehicle
The BvS 10 is an All Terrain Armoured Vehicle produced by BAE Systems Land Systems Hagglunds 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 UK Ministry of Defence (MoD) on behalf of the Royal Marines. The BvS 10 is similar to, but distinct from, the Bv 206 or Bv 206S. It is a much larger and fully amphibious armoured vehicle based upon the characteristic twin-cab, articulated steering system typical of Hägglunds all-terrain vehicles. The main differences from the older Bv206s are a more powerful Cummins 5.9L diesel engine, improved ground clearance, and newly developed chassis, power train and steering units that give the vehicle considerably enhanced speed 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.
