Stalwart

Every military tracked vehicle with track segments (that I've seen) are replaceable one at a time in the field unlike all the earth moving equipment I've worked on that did have a master pin and the segments had to be pressed in and out with specalized equipment.

Regarding the lifetime of tracks, my Scorpion only gets 500-600 miles on asphalt before the pads allow metal contact with the road. Wear is not from chunking but abrasion, chunking mainly occurs with rocks and the like off road.
