You are confusing regular aviation with drones.
One doesn’t have to an officer or warrant officer in the Army, to fly drones.
The Air force is doing their usual, at first their fight was not only that it has to be full pilot flying a drone, but one also on current flight duty, meaning a twisted ankle or temporary loss of flight status, would put a drone pilot out of commission.
I didn’t know that the Army allowed enlisted to fly UAVs.
