Aircraft first saw action in WW 1. The biggest single invention that came out of that war was the Tank, invented purely to storm enemy trenches with impunity.
Machine guns were in use BEFORE WW 1. They were around for the entire war.
It introduced new weapons.
In WW I, the water-cooled machine gun, and the squad automatic rifle were the most modern weapons, honorable mention to the American Colt M1911 pistol. In WW II, the list is very lengthy. The M1 Garand rifle was the most modern military shoulder rifle of all the warring nations, and the bazooka was a new type of weapon during WW II. WW II was the first war to use submachine guns extensively, but they had been invented right after World War I, hence were not "new". Newer weapons continued to be introduced - especially by the United States and Germany - all the way through WW II.
