The IA does at least fire HE missiles at infantryin reaction turns (for player-controlled units). I've tested that to give FAE warheads to modern Russian missiles (Kornet, Krisantema, Vikhr...).
Works fine, except that for some reason the missile's flight isn't shown in extenso as when targetting AFVs, you just see the missile being fired and impacting, like with non-guided shots.

And, yes, apparently no evidence of Metis-M being used (the Syrians only have the old Metis btw), or of Kornets even being fielded. Possibly some have been acquired and kept hidden for future use in really serious circumstances, like the (possible?) Zelzal missiles.
Sounds like the Hizbollah got Syrian Milans, though.
