I don't endorse this vendor or product, but this BAE BvS 10 Viking military vehicle used by the UK Royal Marines (and others) is something to see.
It is amphibious, all terrain combat vehicle and can be configured for troop transport, command and control, repair and recovery, ambulance, and even carrying UAVs.
What is fascinating to me is the combination of the speed and versatility of this thing.
The 2-part vehicle (as well as the front antennas) give the effect of a caterpillar--rocking and rolling--making its way over any surface.
In theatre in Afghanistan since 2006, this combat technology is being tested and improved with additional armor and more power.
As mentioned by Defense Tech, it would be cool if in its next evolution, it could deflect Improvised Explosive Devices (IEDs) like the Mine Resistant Ambush Protected (MRAP) vehicles with their V-shaped hull, which is so important for protecting our troops.
