Oh yes, I love the part with the Guy shooting at the tank with either the Bolt-pistol/slugger... Always have to wonder, why do troops even bother to do that? I'd prefer finding something nice and solid to hide behind and not attracting it's attention!
Though on the animation, it's pretty smooth for flash, especially so considering it seems you didn't copy sprite from page to page.
Though yeah, you'd figure they would be smart enough to put something on their tanks so other people couldn't just run up and hi-jack them, or jet pack on top of them and attach melta bombs as they see fit.
