A tracked articulated vehicle or articulated tracked vehicle, is a variation of a continuous track vehicle that consists of two cars, each with their own track, most commonly with an actuated linkage in between. This configuration allows an articulated tracked vehicle to turn by articulating the swivel joint in between the two vehicles, as opposed to using differential steering to move one track faster than the other.

The Nasu is a tracked articulated, all-terrain transport vehicle developed by Sisu Auto for the Finnish Army. It consists of two units, with all four tracks powered. It can carry up to 17 people, although the trailer unit can be adapted for different applications. There are two main versions, the NA-140 BT and the NA-110.
