Caterpillar Tracks
Caterpillar tracks such as those used on military tanks or construction machines have metal track segments which may be rubber-coated. They usually do not feature tread patterns, because these would offer little additional grip given the weight of the tracked vehicle.

Famous quotes containing the words caterpillar and/or tracks:
“That author who draws a character, even though to common view incongruous in its parts, as the flying-squirrel, and, at different periods, as much at variance with itself as the caterpillar is with the butterfly into which it changes, may yet, in so doing, be not false but faithful to facts.”
—Herman Melville (1819–1891)
“I long ago lost a hound, a bay horse, and a turtle-dove, and am still on their trail. Many are the travellers I have spoken concerning them, describing their tracks and what calls they answered to. I have met one or two who had heard the hound, and the tramp of the horse, and even seen the dove disappear behind a cloud, and they seemed as anxious to recover them as if they had lost them themselves.”
—Henry David Thoreau (1817–1862)
