Finlay finished the two BTR60 tactical air command post (TACP) conversions I started a while back. These will be used as forward air controllers for my soviets. They would usually only have the one but in a very large game two might be justified.
Part of the back edge of the base is painted sky blue to signify their "air controller" roll. This also helps distinguish them from my artillery observers who have a red flash on the back edge of their bases.
