How Many Military Deaths Where There In World War Two ? :)
World War II, by a large margin. World War I saw about 8,500,000 military deaths. By contrast World War II produced between 20,000,000 and 30,000,000 military deaths, along with another 20,000,000 or so civilian deaths. Michael Montagne World War II, by about a factor of ten. Michael Montagne
It had the most deaths of any war.It was more wide spread and the weapons more efficient.
Specify: combat deaths; civilian deaths; collateral deaths; total deaths. Different answers for the two wars depending on the specific question. Far, far more people die in WW2. The greater percentage of deaths in WW1 were military, but the answer is that WW2 was a far larger conflict in virtually all respects.
