What a perfect picture. A M1 Abrams tank is seen frozen in time as it blasts out its 120mm gun, shooting out a giant fireball that looks more like a fire cloud than anything else. It's funny because the rest of the picture seems so calm but that giant boulder of fire is anything but.
The US Marines explain:
An M1A1 Abrams Main Battle Tank crew with Company A, 4th Tank Battalion, fires its 120 mm main gun during the company's pre-qualification tank gunnery at Range 500, Aug. 4, 2015. The live-fire exercise tests tank crews on their ability to work together on target acquisition and accuracy.
