The 120mm is fine as it is. It's in a crappy doctrine, it fires incredibly slowly, its DPS is virtually non-existent considering how often this thing misses and the basis of the unit is RNG.
Apart from the occasional Insta-gib, the 120mm really doesen't pose much of a threat due to its low rate of fire, accuracy and cost (12 ***** pop! Huge drain on your MP income).
This is the only Soviet weapon an Osteer player would sacrifice whole/damaged squads to retrieve. A 120mm in osteer hands would be completely uncounterable with the soviet arsenal. Nothing wrong with one man survivability.
I disagree. If you are careless enough to lose it (taking into consideration its immense range and 6 man team) you deserve to have it stolen.
For those interested, the russian 120mm weighed 280kg. Don't tell me one man can haul that shit away. The smaller 80mm(german) and 82mm(russian) ones weiged 62kg and 56kg's respectively. Still a bit heavy for one man and hence the last guy (correctly) retreats. BTW these weights don't even include shells.

Realism aside, The 120mm is very useful(a lot of power and range) and i dont think its docrine is crappy at all. It shouldnt be retreatable at one man, that is simply a bug that needs to be fixed. Any german weapon captured by the russians can also turn the tide of the battle so this isn't a factor at all. The bottom line is, dont let your stuff get stolen. A german 80mm mortar has effectively 3 men. A russian 82mm mortar is effectively 5 men. The 120mm should also be effectively 5 men. Its just common sense.
Either all mortars should retreat with one man or all mortars should abandon at one man.
