Transphibian Tactical Crusher

I found a small picture of this vehicle in an old encyclopedia of tanks published in 1970 that I found in the subbasement at the UCONN library. Since then I've been trying to find more information on it. I found some pics on the web. This was an engineer vehicle used in Vietnam to clear the jungle. Sort of a mechanical version of Agent Orange. Two prototypes were built by Leterneau and shipped in country for testing in 1969. I guess they weren't too successful, because they didn't build any more, and this was the 60 ton version, and their was plans for a 100 ton version. If anyone knows or sees any more info on this beast please let me know.
