They certainly were years ahead of the Allies in rocket science.

As long as we are speculating, I started this with the timing of the US
invasion of occupied France, June 6, 1944, and saying that things would
of turned out differently if it had occured a year or two later. Care
to speculate on what the Soviet Army would of done too?

When you get the urge to write 'of', consider whether it would be better
to write 'have'. Just a friendly tip.

It wasn't a US invasion by the way. It was a United Nations invasion.
