No, both William and Harry were helicopter pilots, but only Harry saw action - as an Apache pilot! William continued to fly as a civilian air ambulance pilot after his service.
Mea culpa.
Harry did fly choppers.
William flew search and rescue and ambulance choppers after his service.
His first combat though was as a infantry captain in Iraq
Then as a chopper pilot in Afghanistan later to keep him being so much a target...he and his men
