Fascinating, John! Thanks for these shots! Well, the Centurians at the bottom of the last page look pretty much like the colour on my Merk II, and it is a confounding shade, the eye fluctuates between green, tan and grey at will, as if the brain is feeding in different lighting conditions! I guess that makes it excellent camoflage!
The OT-62 is interesting, it sounds like an amphibious APC built on the running gear of a T-62 (though those wheel hubs look more like a PT-76...) Conversion possibilities!
