The Abyss ,
No. Trenches were used in wars as far back as history is recorded. Trenches were used in the Revolutionary war in the US. Some of these trenches can still be seen at the scene of some battlefields such as Gettysburg, Pennsylvania and Yorktown Virginia.
for look the position is used the photography and some time bombs
The dehumanization of men is used as an ironic counterpoint in some Kubrick films.
Barbed wire was used to protect the trenches.
Trenches were used in both WWI and WWII.
Reserve trenches were used as supplies for the trenches out the front. In world war one, they had come up with a technique of hiding in trenches before they fight. To do this properly, they had made them zig-zags. The trenches on the front line were where the soldiers would fight from. Reserve trenches were used in case these people had anything happen to them and they needed to use more trenches and more men. Throughout the war, the conditions of the front line trenches became worse as the communication and reserve trenches improved. I hope that helped :)
Trenches were a trademark of the first World War. They were extensive and elaborate. They were not used in World War II. Are you trying to find out the length of ALL the trenches together?
Trenches in the Pacific Theater of the war were absolutely vital to save lives. They dug them on every island they fought upon. Trenches in Africa, Italy and during the Normandy Invasion, Battle of the Bulge were critical too. The poor guys in the Battle of the Bulge and in the Ardenne Forest had to literally make snow trenches and even sleep in them. Some of the soldiers even used fallen vehicles for trenches and safe protection. Without trenches hundreds of thousands of men would have died, even if some did die in the trenches, especially when they stood up.
A reason I can think of in which soldiers used trenches for is to take cover from machine gunfire. Also, the correct title is why trenches ARE important. Not is.

Trenches were long, narrow holes in the ground used to shelter soldiers in between the battles. These trenches were full of lice, rats and mud.
