For years now the Luftwaffe has been a serious threat for SSU armies. And the Allies have even more dangerous planes than all the other blocs. Soviet armies didn’t had dedicated antiaircraft armored vehicles since the war started, only trucks with multiple machine guns mounted on top. Facing an ever increasing threat from the air, SSU ground troops have asked for a long time to be given a proper weapon system that could deal with such threats and have a good all survivability. They now have been heard with the recent deployment of the MAO ZEDONG. Its quad rapid-firing 85 mm guns are deadly to anything flying, and are pretty useful against all ground targets as well.
