The North American Aviation Rockwell OV-10 Bronco is a turboprop light attack and observation aircraft. It was developed in the 1960s as a special aircraft for counter-insurgency (COIN) combat, and one of its primary missions was as a forward air control (FAC) aircraft. It can carry up to three tons of external munitions, and loiter for three or more hours.
