Hi Joey
Right now I'm building/painting a Trumpeter Type 90 MBT, and the colours (may be...) are the same of Type 89 IFV.
Here is my own mix (Tamiya):
Brown:
33% XF-49 Khaki
33% XF-51 Khaki Drab
33% XF64 Red Brown
Green
90% XF-65 Field Grey
10% XF-24 Dark Grey
The final "look" is very close to the real vehicle. It works!
HTH, and sorry for my poor English
