Considering that the Sino-japanese war takes place just before ww2 i was wondering if some tanks and other amoured vechiles be put in of course there may be some anti tank rifles that can be used to either destroy the tracks or penetrate the amour and kill the people inside. Heavier Anti-tank guns would be slow to move but they are really powerful. there is a 30% chance of a shell to penetrate the Armour and detonate the ammunition killing the tank instantly .Note the Chinese vehicles are from Russia, Germany and Britain as the Chinese were being supplied with these equipment.
