We don't know the origins of this video but it sure as hell gives us the willies.
In the clip which has popped up online in recent days, a military tank identified as a Leopard 2 drives full tilt - this is a 60-tonne vehicle capable of 45mph, let's bear in mind - down a road in what appears to be a military installation of some sort.
In front are a group of 22 men and one woman in suits - we're presuming military personnel - who maintain remarkable composure as the tank barrels towards them before slamming on the brakes, just metres before what would be a messy collision.
Watch and marvel:
The relief on the faces of the group is palpable after the event, with much high-fiving and wiping of brow - although history does not reveal whether there were any underwear-related 'accidents'.
Well, you'd be forgiven if there were, let's face it.
We have no information on where this came from and when it was filmed, but it seems to be legit - watch the soldier in uniform emerge from the left hand side of the frame in the last few seconds of the clip, and the tank driver clamber out.
Question is - would you do it?
