Saw a news article stating that the government of Iraq has ordered “attack jets” to fight the rebels. Article stated it was Su-24s, which wikipedia says is a supersonic attack aircraft.
The Su-25, by contrast, is the Soviet answer to the A-10. It apparently is armored (might be extremely helpful against the rebels firing back with truck mounted machine guns and captured AA guns), has a 30mm cannon similar to the one in the A-10, and is intended for close air support.
