Hi, Pawel.
That's more easily than sculpting a figure and more difficult to cut parts from sprue.
"JGSDF came to give camouflage painting to the main weapon including the tank in 1986.
It is called as "Corrugate curve zonal pattern", brown 3606 was painted on the base color of dark green 3414.
Olive drab 2314 is a basic color before the adoption of camouflage painting.
Inside of the hatch other than the crew compartment such as the tank are still painted in this color. "
Regards.
