Do you sell clothes in the army?
All major cities have military service organs, but they are all civilian products, and imitations can be bought in some places. If you want to buy things in a military vehicle factory, you have to ask active servicemen for help. Their uniforms are badly damaged. You can "bring" them from the military garage with the endorsement of the leader. There is also a need to pay money, and soldiers who lose or damage their uniforms will be punished.
