De-confliction Zone?

 USAF F-15E shoots down Shahed-129 drone in Syria.   It had reportedly dropped ordnance in close proximity to CJTF-OIR Special Ops troops near al-Tanf in what has been called a Russian/American de-confliction zone.   Although obviously Russia's allies in Syria do not recognize that zone.  Shahed-129 is Iranian built, but unclear whether this UAV was remotely flown by the IRGC, or the SAAF, or by Hezbollah, or by Iraqi Hashd al-Shaabi.  Also unclear whether the Special Ops personnel were American or British - both are reportedly at al-Tanf training and advising anti-Daesh guerrilla forces.

The -E version of the F-15 is reportedly dual-role, both air-to-air and air-to-ground.  But has only been used as a ground attack aircraft except for one other air-to-air incident in Iraq in 1991 when it took out an Iraqi MI-24 helicopter, but that was done with air to ground ordnance, GBU-10.  Unclear so far as to whether the Shahed-129 was taken out by 20mm gun, AIM-9 or AIM-120.  The F-15 design is over 30 years old now.  There have been upgrades, but the average age is 26 years and the average airframe had 6000 hours flying time five years ago, probably closer to 7000 hours now.
