The aircraft sparked panic in the ranks of ISIS after bombing its elements and flying in spaces close to the ground, Iraqi News reported last week after a sortie took out several terrorists in ISIS-controlled territory near Mosul. Elements of the terrorist organization targeted the aircraft with 4 Strela missiles, but that did not cause it any damage
Strela-2 missiles have been used against Turkish Army helicopters by the PKK in Northern Iraq. During Operation Hammer; on May 18, 1997 a Strela-2 missile was used to shoot down an AH-1W Super Cobra attack helicopter. Only a couple of weeks later, on June 4, 1997; another Strela was used to down a Turkish Army AS-532UL Cougar transport helicopter in the Zakho area, killing the 11 occupants.[17][18][19] The video of the first attack was used extensively for PKK propaganda and eventually released to the Internet. Greece and Serbia's intelligence services, as well as Iran, Syria, Armenia, and Cyprus were traced as possible sources of the missiles

I am not an IDF procurement officer.
Israelis have their own logic and needs. Good luck explaining to them why they’re wrong.
