Main Body: Robo Cop Ed-209
Left arm: Modular ( Gundum dual gatling cannons or Swampmasher Gatling Cannon)
Shoulder Missle Launcher: Scrap Iron Version 1

I always wondered why the Cobra B.A.T. had to be humanoid looking. So when I saw the Ed-209 Robo Cop toy and thought it would make the perfect Cobra Bat. I have 4 of these all customized right now. I chose to keep the right arms on all of them and envision them as a small caliber machine gun, grenade launcher, and a flamethrower.
The Green one (Woodland) is my anti personell version and it has dual 12.7 mm Machine guns. This I made to go with my Forest Viper line which I will post at a later date.

The Brown one (Desert) is the anti armor version and carriers a 25 mm gatling cannon and two anti armor laser guided fire and forget missiles.

I also have an Urban version painted in various shades of gray to go with my Alley Vipers, and a White Camo version for my snow vipers.

These B.A.T.s are brutes on the battle field. They can with stand a fair amount of punishment but are vulnerable if they loose one or both legs.
