The Rockwell OV-10 Bronco was built as a light attack and observation aircraft and renowned primarily for its Close-Air Support capabilities. It is ca...pable of carrying over 3000LB of external munitions, along with internal space for paratroopers or stretchers. They can still be found flying around here and there, including some use in fire suppression!
While the Bronco still flies in some smaller militaries around the world, it is gradually being phased out by the newer Embraer A-29 Super Tucano!
