Issues
As far as the flash content, I liked it. I could tell you put time into the animation, syncing the sounds, etc. You might want to make the soldiers' voices a little more manly -- they sound twelve.
All that aside, there's no doubt that this is in reference to World War Two. The German bunkers at Normandy, the wepaons, the uniforms, the terrain -- it all adds up to WW2. But I guess it was better that you took off the swastika. For the thousands who died for America to stop a dictator's plans to conquer the world, It's probably better that you did.
And next time, you should have fighter planes fighting and bombers dropping bombs, not vice versa.
