Image Cache: So. Cool. Here's a photo from the US Army showing M1A2 Abram tanks and a M2A3 Bradley fighting vehicle during a live-fire demonstration. Because their cannons have kicked up the sand from the ground, they almost look like desert sand sculptures. But then they start to take shape and you realise that yep, they're war machines.
The photo was taken by Sgt. Brandon Banzhaf. Here it is in full, below.
