the maxim set up/pack up time is still way superior compared to axis HMGS. when spammed it can even supress large blobs of axis infantry.
i disagree with wehr having a better mortar as soviet mortar is 6 man and will out barrage a wehr mortar everytime. along with the zis gun firing nukes, the state of soviet weapon team spam is unhealthy. the soviet mortars also have flare at rank 1 (IIC).
The 1 second faster packup and 160hp extra offsets the deathloop first and foremost, it also ofsetts its worse overall suppression and smaller arc.
The extra 160 hp and vet0 flares offset worse barrage and worse autofire. And having a direct arty counter with increased range at vet 1.
The zis has 6 men and has an arty ability because it has no snare as vet and is weaker as at gun compared to pak 40. And also because soviets lack anything resembeling a normal nade lete alone a nuke nade non doc.
