1945A

Here is a brillantly fantastic short film centered around a Alternate WWII timeline featuring some really good usage of real models and stop-motion without the aid of CGI.

Clipped from Youtube:

It's 1945, and the Allies are on the verge of winning World War II, when suddenly the Nazis unleash an arsenal of super weapons straight out of science fiction turning the tides in their favor. This presentation was done on a VERY small budget. All the tanks and vehicles (Willy's jeep, Stuart tank, Sherman tank, Nazi "Spider" tank) were done with 1:6 scale models, not CGI.
