Do we agree that a 120 mm mortar shell will cause more total HP damage to an infatry in most cases than other mortars will cause?
Look, I don't know how else to say this. The 120mm does not do *more* damage than any other mortar, the AOE is better. Again, thinking about the implications of having a bigger AOE, you can come to the conclusion that it will do more damage over an entire squad.
My point was that the 120mm doesn't have some kind of special damage modifier against units in cover, it's just that the damage is more consistent when it hits units in cover. The important word being when of course. If a 120mm and an 82mm hit a gren behind sandbags right on top of their heads, they will both do similar amounts of damage (leaving a gren squad at roughly 200 health, with 120mm skewing to 190-200 and 82mm skewing to 200-210. I haven't tested volks but I think it's pretty obvious the 120mm will do better there. The 120mm does more damage to the squad compared to the 82mm, but it's still doing the same max damage. It's more consistent when it hits.
For squads out in the open, the 120mm is a different ball game. Of course in this situation the 120mm compared to the 82mm is like comparing a hand grenade to a stick of TNT. Bigger AOE against a spread out squad is a huge advantage. Though squads out in the open tend to be moving around and 120mm struggles against moving targets (save for blobs).
By the way, if you really want to know the reason why I said what I did, it was because I was under that impression myself when I first started playing CoH2. I thought it had some kind of higher base damage. Then when I looked in the stats and found damage all to be the same, and that it was AOE that was the deciding factor, I was surprised. I mentioned it to my friends and they were surprised as well.
120mm is Soviet... its survivability is supposed to be good...
Certainly, but compared to most mortars that can retreat, needing only one model to operate the mortar + run with it is definitely huge. If you get a model drop on other mortars while it's packing up to retreat, you can slow down the retreat a bit, and it can snowball. The 120mm definitely stands out in this regard in that it doesn't need a second man to get the hell out of dodge, so to speak.
I think that the 120mm should be able to retreat, because soviets don't have any kind of FRP. That's a personal opionion, mind you. What about if it moved slower during retreat than normal squads? The thing is heavy as hell after all. That or perhaps it could lose the recieved accuracy bonus that squads get on retreat. Or maybe slower pack-up time to make up for the fact it can't be stunlocked by model drops?
EDIT: No FRP nondoctrinally, no FRP nondoctrinally. That's what I meant.
