Ah YES! That is correct. I had just realized this soldier is from the 25th Karbala Special Forces based in Mazandaran. I'd Imagine mountain warfare training is routine.
If this video is indeed the actual troop movements to Azari border (I have some doubts) then it is an overkill for the threat level...so here is my guess...iran may be getting ready to strike terrorist/ Israeli camps inside Azarbiajan (stand off missile or actual SP incursion). The sizable ground troops are to discourage Azaris or the turks to retaliate..just my guess....
no IRGC buy 2 models of them from DIO,
Lmaooo thought this was Iran-Iraq
