SS Doomtrooper
an excceedingly bad film filled with so many stupid errors it's funny.
A Grey hulk that looked awful, A Tank that only has a driver but can fire away, the tank is clearly a t34 but is called a panther (and to state the fact it is german has a swastica on it), A selectively deaf steropytical english demo expert and loads of other stupid things.

Im surprised thatnoone has mentioned Robo Vampire

this funny atricle tells the story of the movie
