Well, looting, especially small scale looting, was admittedly less strictly prohibited. There were a lot of cases when soldiers would go foodhunting or grabbing something small for souvenirs. Some larger items were exceedingly popular, like cars - grandfather said, that cars were looted in such numbers, that there was special car yards established for keeping the cars taken from soldiers. Again that was not too heavily enforced, mostly because the higher ranking officers too could seldom resist a nice Opel. Also true, that most got away with it. However, the rapes, murders and outright robbery were most strictly prohibited, and were met with capital punishment on the spot. There were no mercy given over such crimes, and they were few in between.
They looted cars?
For some reason that strikes me as funny! How did they get them back to Russia? From what I read, the roads at that time were pretty much mud.
