Good point, Dave. I was an Army Tank Mechanic long ago and far away. Tracked vehicles "throw track" when something gets stuck in the inside, when you spin the tracks on an incline, or whenever else it is inconvienent. Then you almost always need another heavy piece of equipment to get you back up on solid ground get the track and the equipment lined back up straight. I went to tank recovery school back in 1990. Some of the things they teach you are how to "swim" in mud while dragging a 9/16" cable (in order to then drag out the 1" cable) and how to use a cutting torch. My vehicle once threw track 5 times in 5 days (bad track, not bad driving). I never wanted to see a tracked vehicle again after that.
