Landships II

Not a military vehicle at all, but thought some might enjoy it:

"Inadvertently, some of you have helped me with a quest that I have been on for some ten years now, to find more information about a 'crawler-crusher' that was designed and built for clearing on the now-defunct Cross-Florida Barge canal Project. This machine was apparently designed and built for Gregg, Gibson and Gregg, of Fort Lauderdale, Florida, for clearing a 13,000 acre tract of land near Lake Rodman, which was a part of this now-abandoned project.

It weighed around 300 tons, was around 20 feet wide on two tracks, each 10 feet wide, and was powered by two 270 hp Caterpillar diesels. It stood nearly 20 feet high and had a tree pusher bar protruding some distance out in front and was designed to work on a similar principle to the Le Tourneau jungle crushers but in swampy country. In side profile, it looked not unlike many World War 1 tanks but a good bit bigger and heavier."
