The Group is a direct successor to the 17th Pursuit Group, one of the 15 original combat air groups formed by the Army before World War II. The 17th's heritage traces back to World War I, when the 95th Aero Squadron played a key role in the St. Mihiel, Meuse-Argonne, and other Allied campaigns. These battles are symbolized by the seven pattee crosses on the 17th's shield, and it was from the 95th, together with the 34th and 73d Pursuit Squadrons, that the 17th first was formed.
