This picture is part of my "Visions of the Apocalypse" collection, which is intended to be the predecessor to my manga (which is in the planning/character design stage).
It depicts a Russian armoured unit (consisting of T-72/90 and T-80 tanks) rushing into combat against NATO forces, preceded by a huge rocket barrage. Not too much else to describe here.
This work was partly inspired by a particular scene from the Animatrix episode "The Second Renaissance." All work is digitally produced in Photoshop, and required about 5 hours.
