The use of paratroopers began during World War Two. As it is now, being a paratrooper was among the most difficult and dangerous roles in the armed forces. But despite the danger and difficulty, these soldiers proved themselves to be a vital part of many Allied victories.
At the start of the war, however, landing airborne soldiers in the correct location was extremely difficult. For example, paratroopers dropping into Sicily in 1943 were scattered as far as 65 miles from their intended drop zones.
This was no small problem; if airborne troops were unable to land in close proximity to their objectives, they would be rendered completely ineffective. To solve this problem, the military created the pathfinders.
