This is coolbert:
From DEBKAfile material slightly dated but nonetheless germane:
Further evidence [?] that Iran and too Russia have entered the fray in Iraq.
"Al Qaeda-Iraq forces [ISIL] advance on Baghdad military air base. US ponders air strike ahead of Iran and Russia"
"04 July. Al Qaeda Iraq (IS) and Sunni allies were advancing Friday, July 7 on the al-Muthanna military air base at Baghdad international airport, DEBKAfile reports. Three columns, of 1,000-1,500 fighters each, were driving forward in US-made armored Humvees and APCs taken booty. They are also after the assault planes Iran and Russia delivered to the base - eight fighters - four Su-25UBKMs and four Su-25Kms with crews from Iran, and the six Sukhoi Su-25 Frogfoots, along with air and ground maintenance crews from Russia."
MiG-25 called "Rooks" by the Russians and "Frogfoot" by NATO. Ground attack aircraft analogous to the American A-10.
Those ISIL insurgents possessing Stinger MANPAD that is effective against the MiG-25. Also that military airfield adjacent to the international airport? Deny that international airport and big problems for the Iraqi government even beyond what is already.
