In Rainbow Six: Ravenshield, these are the terrorists that glide across the map on their knees instead of running.

Mostly, it reflects poor AI node placement by the map maker. Often, these tangos are the hardest to kill because their animation is much faster and erratic.
Ah shit, that last tango is a knee glider. Anyone have a flashbang left?
