How did weapons affect World War 2?

This question appears to be ambivalent, either you mean there was a lack or a surplus of ammunition supplies. whicheverway you look at it; it certainly caused a lot of disruptions, destructions,pains heartaches and a lot worse which I dare not elaborate.I don't mean to be rude but to the contrary, helpful and practical. If you just type wrld war 2 in your search engine, it will unleash you with enough ammunitions about the hell WW2 created around the world. You will also, perhaps, get an accurate answer about ammunition supplies and a lot more.I won't say it will make interesting reading but it will certainly make useful reading.
