I never was taken thru the area where they painted the tanks, but seeing batches of them on flat bed rail way cars: you knew right away they were painted via robotics. The paint jobs were identical on brand new tanks. This tank was probably hand sprayed as you would have to re-program the robotic heads to change the pattern.
That is Lima, Ohio! To the rear of the tank is the test track that every tank must go thru. And even further out is the farmer’s silo that had the bull’s eye painted on it to test the sighting system.
