The Curtiss Super Hudson was a pusher biplane of the US air forces during the opening of the Great War. They were liked by pilots who flew them because it gave them a better view of the ground, and allowed for a machine gun to be mounted in front of the pilot. This was a tactical advantage over the Canadians who flew Avros whose only machine gun was operated by the front observer.
However, by December 1914, the Canadians had started flying in multi-aeroplane formations so the Americans needed to do the same. The usual observation flight consisted of four Curtiss aeroplanes in diamond formation, ready to break off observing to attack or defend. Lt. Jonathan Moss, as flight leader, also took the initiative to attack supply columns behind enemy lines by diving and machine gunning them when opportunity presented itself.
