My weapon was poison gas. Germans would put the gases in to the grenade, and fire them at the other side.Germans introduced My weapon is poison gases. Fritz Haber was the inventor of the first poison gas. Germans would put these gasses into the grenade, and fire them at the other side. Germans introduced poison gases in 1915, but French used a little bit of tear gas in 1912.
This weapon would effect soldiers near the front lines in Europe becasue the opposite army would fire it at the other side and the soldiers would have trouble breathing, and troubles in their lungs. It would be same with Civilians near the front lines in Europe but it would be worst because Civilians would probably not have any equiment on their faces to block the gases out.
Pros and Cons
A negative consequence of this weapon is that you don't know it it gets in your body before you know its in it. The only way you can tell its in your body is because of the smell and it takes a while for the smell to get to the air out of the grenade. A pro is that poison gases was able to kill within the trenches.
Modern day improvements
This weapon was improved from world war one because as the years have gone on technologies has very much improved and gotten better. So any flaws that was in the Poison Gases in World War 1 they have been fixed and probably even more improved. People have been making new ones ever since and there is new ways to deliver it too like mailing it.
