Possibly my greatest work to date

Me and my mate Lanky used to have this thing were we would take the over world with our seperate factions, the Black Dragon Army (Lanky) and the Red Nerve (Me).
We would also come up with weapons that fits those armies unique "style", my style was very Mad Max sort of post apocalyptic machinery, very rusty looking yet very quite powerful, inspired mainly from Command and Conquer concept art.

This was one of my very first Idea's for a weapon... a Shotgun tank... concept sketches of such a machine began waaaay back in 2004 and have taken the form of Sketch book scribbles, 2D drawnings in Paint (before I figured out Photoshop) and full 3D models in GMax, although, very shoddy.
This is its final, glorious looking self. Equipped with Dual 40mm Cannons that fire large, shotgun like Shells loaded with explosive pellets. The R5-40 can Pepper Aircraft with un-rivaled accuracy devastation. Also equipped with a mounted searchlight for those Nightime skirmishes. The R5-40 turret can also be lowered to provide Anti-Vehicle fire when loaded with Sabot Shells.

Sorry for the long description... there is alot of history behind that tank and I think i've done it justice
