What did they fight with in World War I?

Answer 1

What kind of weaponry are we talking about?

Small arms would be rifles mostly, like the Lee-Enfield and the Kar98k. Towards the end of the war the Germans invented the sub-machine gun, the MP18.

Machine guns like the Lewis and the Vickers played a huge part in combat. It wasn't the small arms that slaughtered, it was them.

Big guns, such as artillery were also very common. All sides used artillery to soften up targets before an attack.

Tanks also were invented during WW1 by the British. Both sides started to use them towards the end and the only things that could take them out were artillery, other tanks and mechanical failure.

Naval battles didn't really occur hugely in WW1. The Battle of Jutland only claimed cruisers, no battleships. The real naval battle was the submarine one. Submarines played large roles in attack supply ships, in fact it was a submarine that eventually caused the USA to join the war.

Aircraft were another new invention. Both sides started to use them, sometimes as spotters, there were bombing attacks, both civilian and military, though the bombs were not very effective. Dogfights between sides were common too (Look up Red Baron and Alfred Ball) with aces starting to come into play.

Mine warfare is largely overlooked. One side would tunnel under the other side and plant a giant explosive underneath. They would then detonate it with great effect.

I hope this helps, there's a lot more I could go into, like Laurence of Arabia, but that may be slightly different from what you are looking for.
