The OV-10 (twin turboprops) was used quite a lot for CAS (by the Navy
mainly, see "Black Ponies") during Vietnam. And since then by the
Philippines, and probably Venuzuela (sp?).

It was designed for Counter Insurgency (COIN) operations, which was
usually defined as low threat ops including CAS (but that was before
the SA-7 appeared!).

Great plane in a relatively low threat environment. Sucks when there
is radar guided AAA or manpads around - as Marines found out during
DS. Just too slow to get away from the threat!

Fun plane to fly, though, and a great FAC platform.
