Fighting in the trenches was a lot safer than on open ground, but it was still not an ideal place for a soldier to be. Both the German and the France had many difficulties while preparing, and fighting in trenches.
Many new weapons were introduced in World War I. They were the machine gun, tanks, poison gasses, flame throwers, grenades, air planes, and trench mortars.
Many times the weapons were of great asset, but the larger weaponry was harder to move through trenches, or around trenches. These weapons were tanks, and larger guns used against the opposite force.
Living in the trenches was dramatic and unstable. The soldiers had a limited amount of space, and always had to be aware because an open fire could easily begin at any time. Not only did they live in dirt, mud, water, and blood but they had to do so shoulder to shoulder with another soldier with hardly any room to move.
Daily deaths often occurred wether you were laying down in the trench, or standing outside of it. The enemy often open fired at a trench, and usually a soldier was caught off guard and shot. Many soldiers were shot from precisely aimed sniper shooting.
The soldiers had to live with various diseases passed around from person to person. They also had to live with the daily boredom. While they were on guard, most of them also just stood alert in trenches all day with little entertainment.
