In principle, there were already paratroopers during this period, and the first to use them was still the German Army.
Ordinary reconnaissance on the battlefield required scouts to cross several defenses from the ground, surviving with great difficulty, often only a few could infiltrate behind enemy lines to conduct reconnaissance.
The probability of successfully completing the task and then relaying the information back to the German Army was almost zero.
Thus, the German Army used a creative tactic where their scouts would use the cover of night to board aircraft, cross enemy lines, then parachute down to carry out their mission.
This was considered the prototype of airborne troops.
(Note: The earliest combat record was in 1918 when the Italian army used modified bombers to air-drop a unit behind Austria-Hungary for sabotage missions. The first regular airborne troops were formed by the Soviet Union in 1930.)
