The Air Service 102d Aero Squadron was organized at Kelly Field, Texas, on 23 August 1917.
The men engaged in construction activities, drilling, digging ditches, making roads, and putting up tents for new recruits arriving at the field.
 When athletics were started at the camp, the 102d organized a baseball team which was runners-up for the championship at the field.
  Once basic indoctrination training was completed, the 102d was ordered for overseas duty, being ordered to report to the Aviation Concentration Center, Garden City, Long Island.
 It arrived at Mineola Field on 3 November 1917 where it was prepared and equipped for overseas duty.
 On 23 November, the squadron, along with the 103d, 104th, and 105th Aero Squadrons were ordered to report to the Port of Entry, Hoboken, New Jersey for boarding on the former White Star Liner RMS Baltic for transport.
 After an uneventful Atlantic crossing, it arrived at Liverpool, England on 8 December 1917.

After a few days at a Rest Camp near Winchester, England, the squadron moved to Le Havre, France, and then traveled by train to the Replacement Concentration Center, AEF, St. Maixent Replacement Barracks, France, arriving on 18 January 1918.
At St. Maixent, the 102d was used as a station squadron, as well as being trained in hiking, fatigue duty and guard duty.
  On 1 March, the squadron was ordered to report to the 2d Air Instructional Center (2d AIC), Tours Aerodrome, in central France.
 The men were assigned to nearly every department at the field, in the machine shops working on aircraft to the transportation department where the men drove trucks and all manner of vehicles.
