How did tanks (just invented) play a part in WW1?
In World War 1 tanks first appeared at the Battle of Flers-Courcelette in September 1916. It was the first time tanks had ever been used in a military conflict. They were commonly armed with a cannon and machine guns and were bulletproof. They plowed threw anything in their way either it's people, a small tree, or a barbed wire fence. They accompanied foot soldiers in battle but could only go 4-5 mph at the most. The small ones weighed 5-10 tons while the bigger ones weighed 15-20 tons. Some had special abilities such as propelling themselves through water. They could easily go through trenches yet they were very stuffy and soliders working in them often breathed in a lot of fuels, this is the reason some army's turned down using them.
