The Bucks Laevis DD5b is a transformable drone, which can be switched between remote control or intelligent exploration modes, and has both compact and expanded forms. In compact form, it has the ability to travel speedily by rolling in a barrel shape and can cover mines or traps on the road, thereby opening up a safe route for the convoy. When expanded, it can move quickly on three legs, searching for hidden enemies in narrow spaces, such as collapsed ruins. Its expandable module can be equipped with weapons, such as machine guns and mine laying systems to wipe out garrisons.
