A razor wire rapid deployment unit (RDU)/barrier is disclosed. In some embodiments, the RDU includes an enclosure having a first section coupleable with a second section, the enclosure defining an interior area therein. The RDU may further include a razor wire disposed within the interior area of the enclosure, a first end of the razor wire directly coupled to the first section, and a second end of the razor wire directly coupled to the second section. The first and second sides of the enclosure may be separated from one another to deploy the razor wire from a compressed configuration to an expanded configuration.

A vehicle stopping device includes a casing configured as an open enclosure having an open side, vertical side walls, a horizontal top wall and a horizontal bottom wall forming an interior space of the open enclosure. A pair of caltrop bars are configured to be securely stored within the interior space of the casing in a stored position, and are configured to be activated from the stored position to a deployed position in which the first and second caltrop bars extend out of the interior space of the casing through the open side thereof for positioning on opposite sides of a vehicle tire. Each of the caltrop bars being formed of a bar and one or more caltrops arranged along the bar for puncturing and deflating the vehicle tire when the vehicle tire is driven over the caltrop bars.
