When the whole world was at war with each other this became known as world war 1.During that time weapons weren't like they were today.The weapons used in world war 1 changed the way soldiers fought in war,they had many uses,these weapons revolutionized the way we fight modern warfare today.
Lets start from the smallest weapons,in world war 1 many soldiers used melee weapons such as trench club.These weapons were mostly used in trenches which came to be known as trench warfare.
Bigger weapons were also used,such as rifles for example the British ocentric rifle
Now you may think that wars were fought in certain kind of battlefields but war was fought everywhere such as Arabia,there many soldiers used a rifle called the Lawrence of Arabia named after British soldier T.E Lawrence
As i said before everyone used everything they can to their advantage this meant taking war to the skies.But creating the first airplanes was troublesome,the first attempt to create an airplane counterpart took place in the US.One of the planes used in war was the P-38 lightning plane such as this one.
