There's really no self defence system for drones like these except for DIRCM and actual lasers. Chaff and flare is used in conjunction with defensive flying. Aksungur or any other MALE drone cannot fly defensively. A simple barrel roll is not a defensive maneuver as well. DIRCM and lasers are expensive and use a lot of power, something Aksungur doesn't have with its two diesel engines. So you either don't fly them over contested areas, or accept the possible losses. This instance is of course unprecedented, as the area was more than likely deemed safe prior.Most of the uavs of Turkish army do not carry SAR payload,so they sometimes fly under cloud for observation,and this lead to low altitute mission and bring risk of being detected,targeted finally shot down.Akıncı and Aksungur uavs are not cheap,we have make some self defence system for them.
It is too soon to talk about this. With what's available, I'm leaning towards Iraqi central government trying to set some boundaries re its defence agreements with Turkey, especially re Kirkuk. Person who announced the action is an Iraqi general from the air defence command, with no known direct links to PMF or Iran. From an outside perspective, Iraq accepts Turkey's COIN operations in the north, as they are mostly powerless there anyhow, but they have been trying to rein in cities in the north(with our help in some cases) for the last 2 or so years. When we strike our targets in Iraqi cities, this also hurts the government's sovereignty.
Or, this is just Iranian elements in the army forcing their way and create a low trust situation between Turkey and Iraq. If that is the case, it would mean Iraqi military is even more fractured than previously thought post 2018, and the possibility of the Development Road going through to finish line just seems like a fool's errand. We simply lack the tools to handle Iran in Iraq.
