BUR #50005 has been approved by @evazion.
create alias tank_treads -> caterpillar_tracks
Utility alias. The singular concept of "treads" on tanks is almost universally caterpillar tracks. However, not everybody thinks of the words "caterpillar" or "tracks" when their aim is a tank or something like Napalm Man's treads.
