These are mostly Tamiya and Bandai kits that I have built and mounted onto flatcars. I do not follow strict DOD transport protocols as I personally dislike tank turrets facing backwards, tarped gun muzzles, and empty machine gun cradles... However, tie down hard points and chocks are as accurate as I could make them.
