Christopher Mrosko has posted Part 2 of his picture gallery of the U.S.M.C. in Beirut, Lebanon in 1983. There are lots of good shots of M60A1 Rise\Passive tanks undergoing track maintenance. I spent many hours "walking track" and beating end connectors back on with a big sledgehammer. Tracked vehicles require a LOT of preventative maintenance if you don’t want them to become untracked vehicles.
This is a really good collection of clear photos.
