as well the germans experimented in all sorts of impractical weapons. of course some of these lead to breackthroughs like the first cruise missiles (v1 and v2) and the first succesful jet powered warplane (meschershmit ME262) and all sorts of cool stuff like mini subs and rocket launchers. as well as a canon so big it had to be assembled on a railroad track! (railroad guns like anzio anne)
they also made the BEST tanks like the tiger and the panther.
for future refrence the americans had a bad tank the sherman. it was bad cause the front gun was crap and the armour was useless against tanks (in all fairness britain's tanks sucked even more however they were the ones who managed to put a decent gun in the sherman.)
the only reason why the sherman was a GOOD tank is cause it used car parts (easy to repair and drive) it was cheap and easilly mass produced.
the sherman was always outclassed though.
the war was not won at d-day by the way. it was won at stalingrad (3 million germans died on that battle in the eastern front.
finally
MERRY Saturnalia now give me my gift
