During the years of uncertainty and territorial gain was a necessity; the US participated in one of the major wars of all mankind, also known as The Great War. The onset of war and the outcome of wars were significant in forming the foundation of America today. During World War I, significant elements such as the weather and terrain played a major role in the outcome of war and combat operations within the area. As the possibility of war surfaced and became inevitable, it was apparent that the terrain and weather had no favorites on the outcome, it did one of two things; it either helped one force or provided a stumbling block for the other. The terrain and weather provided advantages and disadvantages depending on the mastermind behind the strategy. When thinking of the terrain, it is imperative that the commander considers factors such as hills, mountains, streams, rivers, and valleys that can influence the type of operation executed (Headquarters, Department of the Army, 1993). The terrain can affect the movement of personnel, functionality of equipment, survivability and dispersement of troops. The weather is very crucial in the onset of a Soldier's morale, level of performance and quite important the ability to survive.`
