Looks like Iran is slipping Iraq some jets on the low-low
According to the BBC, Iran has supplied Iraq with attack jets to help it counter an offensive by Sunni rebels led by the Islamist group ISIS/ISIL.
The jets, Russian-made SU-25s (NATO reporting name Frogfoot) are low-key strike aircraft comparable to the U.S. A-10 Warthog (but without as much armor or smart-weapon capability), seem to have come direct from Iranian Air Force stocks. Since ISIS is a Sunni group (and Iran is the largest beehive for Shiites), Iran has a vested interest in keeping these insurgents on the run.
As far as the jets go, they make a good fit for Iraq as they used to fly the same model (albeit with Saddam-era Sunni pilots), and are easy to operate and maintain. Plus the Iranians don’t have to worry about these handful of counter-insurgency aircraft being turned against them in a real way should the two countries ever return to the old 1980s says of open combat.
And by making brownie points in rushing these old Froggers to Baghdad while the Iraqis are still wait-listed for brand new Block 50/52
F-16s coming from the U.S, the Iranians are loving it.
