During World War I, March Field was a major primary pilot training base for the Air Service,[1] with its graduates being sent to advanced training schools before being deployed to the American Expeditionary Force in France.

In July 1919, Congress authorized resumption of enlistment of flying cadets on a limited basis, and the school at March Field was re-opened which offered a combined ground school and primary flight training using surplus Curtiss JN-4 Jennies.

Even before the school at March opened, it was known it was a temporary unit, as plans were ongoing to expand the facilities in San Antonio.

[3][4] The group was activated again in 1943, but Standard military units, based on relatively inflexible tables of organization were proving not well adapted to the training mission.
