A propulsion unit includes a platform, a propulsion assembly, and a tether. The propulsion assembly facilitates selective launching of a tire deflation device from the platform. The tether is coupled to the platform and is configured for attachment to a deflation device.

A bracket for a wheel stop barrier for wheeled equipment or machinery. The bracket comprises a base releasably securable to a floor or a surface over which the wheeled equipment or machinery is operated, and a barrier retainer to releasably secure a longitudinal barrier rail to the base. The bracket limits movement of the longitudinal barrier rail, across the floor or the surface when the base is releasably secured to the floor or surface and when the longitudinal barrier rail is contacted by a wheel of the wheeled equipment or machinery. Also disclosed is a wheel stop barrier for wheeled equipment or machinery, where the wheel stop barrier comprises two or more brackets and one or more longitudinal barrier rails.

A vehicle barrier includes a beam extending longitudinally between opposing end posts, the beam positioned vertically above a ground level and separating an asset side from an attack side, the beam comprising beam sections and a crash post positioned in a same vertical plane as the beam, wherein beam sections are pivotally connected to the crash post.

A vehicle mitigation system a barrier hauler and at least one barrier. The barrier hauler includes a stem, a handle positioned at one end of the stem, and at least one wheel positioned near an opposite end of the stem, the wheel capable of rotating relative to the stem. The barrier hauler further includes a lift arm having an engagement pin, the lift arm rigidly fixed relative to the stem and disposed at a first angle to the stem. The barrier includes at least one wheel positioned at a first end of the barrier to act in cooperation with the at least one wheel of the barrier hauler when the barrier hauler is engaged with the barrier.

The present subject matter provides a dissecting element that comprises a flat body having an upper side and a bottom side and opposite edges; a hinge on the bottom side wherein the hinge is connected to a surface, wherein the dissecting element is configured to move between an erected state in which the flat body is in an upright position and a horizontal state in which the flat body is adjacently lying on the surface. A plurality of dissecting elements can be provided on a portable ramp and several dissecting elements or ramps establish a barrier system. A method is also provided to prevent passage of vehicles using the dissecting elements.
