Some fun comparison of Hezbollah and Hamas :
-Average Hezbollah fighter has better gun competence than average Hamas fighter (due to various reasons, one of which being having access to lots of ammo they can expend )
Hamas nukhba elite force however is on a high level of training and competence. Problem was Hamas nukhba force is based out of Beit Hanoun/Beit Lahya in northern Gaza and eastern Gaza (Shujiyieh) and a few areas from central Gaza but mostly these areas. This force went into Israel on October 7, a lot refused to come back and died fighting there. Some came back and put up the best fights which is why these areas were targeted severely right at outset of war leaving lower level Hamas troops to defend from invasion
-Hezbollah is a lot better at deploying mortar fire accurately and conducting long range ambushes of Israeli armored corps
-Hamas has hit and run advantage, due extensive tunnel system and can more easily retreat into tunnel shafts
-Hamas knows Israel better (because it's occupied Palestine) and had very good knowledge of everything in the Gaza envelope, it had better infosec capabilities than Hezbollah and was able to get to many targets on October 7, Hamas's incursion into Gaza envelope is a capability people didn't they think had
Hamas ability of hostage taking and taking them back to Gaza as prisoners and securing their whereabouts is a lot higher than Hezbollah's
The Hamas incursion into Gaza envelope is more sophisticated than Hezbollah plan to take over upper Galilee region
However, pre -2023 Hezbollah could likely hold Galilee for longer than Hamas could hold Gaza Envelope and could provide impressive and effective support fire using rockets and mortars, they would be able to more precisely target IDF than Hamas could. And more rapidly execute such an operation
Hamas's rocket fire on October 7 was partially to send a message and not just operational based (targeting IDF forces around Gaza ). We can say it's a 50/50 or maybe even 40/60 split. Hamas relied more on storming the area and seeking out IDF forces.
A Hezbollah incursion into Galilee would be a ton of rocket fire that is operational based meaning trying to paralyze IDF forces all across northern Israel and also immediate attempts with short range ballistic missiles to target Israeli air bases across Israel
Meaning IDF would be in bigger trouble compared to a Hamas Gaza Envelope scenario where they can regain control more quickly, they would face a bigger set back and take more days to regain control
Whereas they took a blow from Hamas but can regain control. However the bigger problem for the IDF was Hamas taking 250-300 prisoners back into Gaza. Which posed a big challenge for them
Hezbollah likely wouldn't take prisoners back to Lebanon but would take hostages in northern Israel to complicate IDF efforts to regain control
Israel would likely butcher Lebanese civilians though and it's unlikely Hezbollah would be angry enough and have the balls to do execute that plan whereas Hamas was angry enough and had the balls to do that despite it going badly for them and the people of Gaza
- They both have good snipers. Hezbollah has experience from Syria but doesnt need to utilize snipers much in southern Lebanese villages. They will come into play in other regions, particularly cities, not villages
