in this video it shows how horrible trench warfare was and how bad soldiers lives were in trenches like on how they couldn't leave the trenches unless they wanted to get blown up and on how weapons improved during war to help soldiers this video proves that during war soldiers suffer alot of hardships and for sometimes nothing like for example Russia lost millions of soldiers and then they drop out of the war this shows how pointless war really was
