First Hezbollah never fought a guerilla warfare.
Second the launcher shown in Hezbollah video only showed in iran in 2011-2012.
Second Sayyad is 3rd of khordad , it's Bavar-373 it's 15th of khordad .
It's pretty much going to be the backbone of our airdefence so I rather we won't give it to every body.
Also look at 3rd of khordad system which is the smallest Sayyad deployment and tell me how Houthis gonna protect it. And how it's guerilla warfare equipment.
If you want to give Sayyad you must give a tellar and if you want sayyad2 be sayyad2 you must give them Bashir radar.
If you want to give them 15th of khordad then the situation is worse and you must give them the radar otherwise the system is useless
