Question for panzer campaign stalingrad

[Sharky]

so i should back as many troops from the city to plus the gap in the north ?

also, can you tell me how to use anti tank gun ? they seem not so effective, especially the 37mm german one, you have to put it in transport mode, unload in front of the ennemy, likely suffer casualties in the process, and... nothing...

i think i haven't tried the 88 because no one want to sit in front of it, but still, 37 should be able to do something no ? i no it doesn't have an awesome reputation, but still should be useful.

also, how to use the salf propelled AA ? are they usefull as meatgrinder ? assault or pure defense ?


thx for the help anyway !
