Narrative:

While hover taxiing at a [military] training field a quadcopter drone (app. 2ft by 2ft) flew overhead of my helicopter at roughly 200 ft AGL. The training field is 1 square mile. My aircraft was in the southeast corner of the field. The drone flew over my aircraft then to the northwest until it eventually exited the training environment. There were 9 other helicopters at the field during this time. The drone flew overhead at least 3 other aircraft that were doing hover training during its transit across the field. [Military] operating altitude at this outlying field is 650 ft AGL and below. I made a call over our common training frequency to alert the other aircraft and also had the field duty officer file a report with local law enforcement.
