Question for panzer campaign stalingrad

[Sharky]

Hi,

I have an ongoing game as germany on the stalingrad ss to the rescue. I'm a beginner and i have some problem to understand how to best employ troops. I successfully cleaned the northern part of the city but the southerns pocket are hard to crack. Can you tell me what is the best way to do so ? I have some unit I don't really understand how to use, like self propelled aa artillery and so on. Is there a way to quicken the reduction of the pocket by fine tunning or do you have to use brut force ? I tried to "desorganize" units in the pocket but hard to do it for all...


Thx
