Footnote: The United States military used the same basic bolo knife from the turn of the century all the way through to the Second World War. First the bolo was only issued to the Hospital Corps in the fields where the long machete-type weapon was mainly used in jungle-type surroundings to clear brush and for any task requiring a "chopper". The Philippine-American war of 1899-1902 was where American troops began to use this local weapon, and realized its usefulness. In the Philippines, machetes were called bolos, and this name stuck even as the knife went through several changes in its appearance. After the military had less use for such a long weapon, the bolo was considerably shortened. It was then issued to troops needing to clear their field of fire, such as machine gun squads.
