I think the fighting in WWII was gruesome and violent, many soldiers killed or severed. I think the fighting in WWI was different because while WWI was fought in the trenches and used machine guns and poisonous gas, WWII was fought using modern artilery and machines utilizing more airplanes, ships, tanks, and submarines. Special operations methods were also developed during this war togeter with atomic misiles and secret comunications.
Explanation:
Hitler's invasion of Poland in September 1939 drove Great Britain and France to declare war on Germany, marking the beginning of World War II. Over the next six years, the conflict would take more lives and destroy more land and property around the globe than any previous war.
Opposing sides were dug into trenches, which led to higher casualties and poor conditions for soldiers but they could rarely advance because of improved technologies such as machine guns which gave a tactical advantage to defensive forces and artillery.
