What were the three most important weapons used in World War I?

Answer 1

The 3 weapons that were used primarily in WW1 were machine guns, poison (mustard gas), and airplanes. There were also tanks and submarines too. Don't forget rifles, pistols, and granades those were also important

AnswerArtillary was the most important. Most casualties (by far) of WWI were killed by it. Gas and planes played only a minor role (gas was used a lot but it wasn�t very effective).

Don�t forget the flamethrower!

AnswerActually the Airplane was a major part of World War 1. It would be able to Spy on enemy postions and give the coordinates for the artillery to fire at. It would also be able to go over an enemy base and throw down grenades for much damage. The airplane is what could make or break either side. AnswerContrary to the above, the airplane was a non-entity in World War One. It was too technologically immature to allow for effective attacks against the ground, so its impact on land warfare was limited to aerial reconnaissance. Such recon, while useful, was hardly decisive, as the vast majority of combat was over fixed (and well understood) ground.

The weapons that had the largest impact on the fighting were the Machinegun (as the primary tool which enforced trench warfare, and altered the complete strategy of war), the submarine (which radically altered the nature of naval combat in a way not seen for centuries), and the artillery piece (artillery fire caused more casualties in WW1 than any other source, and quadruple the percentage it had in previous wars).

The tank, while more decisive than the airplane, was not really ready yet for combat, and played a limited role in the war (the large victories in 1918 by Allied forces had little to do with tanks, and much more to do with changed infantry tactics and the fresh infusion of American troops).
