That green one, I'm not sure, but it looks Border Patrol green. BP green is lighter than FS green and more of a lime-green. Not that it matters. Depending on the location, a BP vehicle will be beat up more. A FS vehicle stays on a dirt road more. Whereas, BP vehicles tend to stray onto and also off, trails more.
I have a US Fish and Wildlife Sub...I think. It was tan and the PO thought that it came from the BLM. I don't remember BLM having tan vehicles, but I know that US FWS did. Mine has, now, 190K on it. 4=speed and 3.42 gears. It was just what I was looking for....locking hubs, a straight axle and a lever on the floor to grind the transfer case and not a button. I saw it in the Thrifty-Nickel and gave the owner a call.
I plan on keeping it a long time.
