Have you ever seen anything like this? A KC-130 refueling a helicopter that just happens to be carrying a Humvee.
A KC-130J Hercules, assigned to Marine Aerial Refueler Transport Squadron (VMGR) 234, is staged on the flight line at Marine Corps Air Station Cherry Point, N.C., Feb. 23, 2017. VMGR-234 assisted Marine Heavy Helicopter Squadron 464 in an aerial refueling training operation to maintain interoperability.
