What armory did soldiers use in World War 1?

Answer 1

They used trenches, artillary, tanks, posion gas, and machine guns. The trenches provided protection, while the posion gas and flamethrowers could counter the protection provided by the trenches. The machines were effective when there were troops out in the open, but useless against the tanks, just like the barbed wire, which created an obstacle for the troops. The artillary were fired from the back and they were used for killing enemy troops without losing any of their men.
