World War 1 is described to be one of the most devastating wars recorded in history for a number of reasons. One of the reasons was the tactical use of chemical warfare, which was predominantly used as a weapon. Most of the course of this war was fought in trenches, strategically built for optimal leverage from either side of the line. Trenches offered substantial protection from artillery and small arm fire. However, this often resulted in a stalemate. This eventually led to a new era of weaponry involving the use of chemicals. These chemicals were specifically designed to hinder the physical capabilities of soldiers. They were capable of severely weakening and even killing soldiers.
