WW2 German Mod

[Imp]

Please, don't be so serious. In fact idea is fun (at least my opinion). It would be nice to see whole timeline 1946-200? battles with modern equipment vs. (nazi?) Germany. Result: one sided slaugter? Ok, it could be surely in "real world" but what if german scientists/developers had possibilities to develop German arsenal (not only nukes) better than they were in reality until May 1945...

Its easy to do if time dependant but why not just do in WW2 assume timeline from mid 45 every month = 3 or 6 months & build OOBs based on that sides strengths or paths taken so advances.
Make the assumption nukes are a failed project but everything else develops faster driven by the continued war & supply building is not a problem.

Germany better guns firecontrol range finder possibly rocket arty or weapons first to invent poor quality ATGMs
US Giros vision aids armour as they dont like losing men, also always have worst guns best airforce, the attack helo. Big vehicles profile seems disregarded. Claymore type weapon for vehicle infantry defence.
Russia speed & small size flame weapons. Big guns with low ammo loads
Brits Advanced armour specialist vehicles the tank slow pokes armoured cars, decent guns (probably should have giros & vision instead of US as US seemed to neglect after the war). Radar AAguns

Giving them all national characteristics so US could take current models up armour (losing speed till improve power plant) improve giros. They would improve in other areas just not as quickly.
