Massive Frontal assault
Commanders on either side believed the only way to gain any ground in the war was to put on a massive frontal assault where all soldiers in the front line would jump over the top of there trenches and march through no mans land in a line towards the enemy. This was believed to be one of the greatest horrors of war because once you are called upon to do this you must charge forward and if you were to retreat without order, you would be shot by your own country. This was one of the most unpopular activity among soldiers.
