The Japanese, through bitter warfare, have become masters in the art of camouflage. When vehicles can no longer be serviced they are not wasted – the Chi-Ha can now continue as a dug in emplacement:
The Empire of Japan valued it’s navy greatly, so much so that valuable metal and other assets were prioritised to them, naturally making other fields suffer. However ingenuity was still fresh and victory was still in their sights, they became rather creative with their tanks that they struggled to maintain. The Chi-Ha naturally struggled facing against American Armour, so it was time to bunker down and create ambushes.
These tanks became immobile turrets, forsaking mobility for additional protection by having a lower profile. The Chi-Ha was already relatively small and digging it in just increased it’s deadliness. Sometimes lying in wait, or being used to fortify defensive positions, they are an effective edition to any army or gaming table!
