A vehicle includes a passenger capsule having a first end and a second end, a front module coupled to the first end of the passenger capsule and including a front axle assembly, a rear module coupled to the second end of the passenger capsule and including a rear axle assembly, and a braking system. The braking system includes a pump, an actuator including a rod that extends through a brake housing to apply a biasing force to a brake and inhibit movement of the vehicle, and a line coupling the pump to the actuator. Engagement of the pump provides a pressurized fluid flow through the line that overcomes the biasing force and releases the brake.

A vehicle including a frame, a cabin, and a blast mat. The cabin is coupled to the frame and includes a seat and a series of walls. The blast mat has a bottom surface engaging at least one of the walls. The blast mat includes a first portion configured to support a first portion of an occupant seated in the seat and a second portion configured to support a second portion of the occupant. The first portion of the occupant and the second portion of the occupant have different resistances to blast energy. The second portion of the blast mat has a greater thickness than the first portion of the blast mat.

An arrangement for ballistically protecting a driver or passenger in a civilian vehicle comprises: (a) a back ballistic member mechanically securable to a rear surface of a back of a driver or passenger seat; (b) a first side ballistic member connected to the back member by at least one hinge such that the first side member is angularly displaceable relative to the back member; the first side ballistic member comprising a transparent ballistic portion; and (c) a second side member connected to the back member at an opposite side of the back member. The second member is linearly adjustable relative to the back portion such that mechanical contact between the back of the driver or passenger seat is provided. The ballistic back member comprises at least one adjustable telescopic strut configured for abutting against a vehicle floor and supporting the ballistic back member during driving.

A brake system includes a brake actuator configured to engage a brake to limit movement of a tractive element, an air-to-hydraulic intensifier coupled to the brake actuator where the air-to-hydraulic intensifier is configured to receive a supply of air and provide a hydraulic fluid to the brake actuator based on the supply of air to overcome a brake biasing force of the brake actuator to disengage the brake actuator from the brake to permit movement of the tractive element, a hydraulic reservoir coupled to the air-to-hydraulic intensifier, and a valve. The valve includes a first port fluidly coupled to the air-to-hydraulic intensifier, a second port fluidly coupled to the hydraulic reservoir, a third port fluidly coupled to the brake actuator, and a valve gate that is repositionable between a first position that couples the first port to the third port and a second position that couples the second port to the third port.

A lightweight ballistic armor system comprising at least one metal strike face plate, a laminate composite backing material secured to the at least one metal strike face plate and an optional air space provided between the metal strike face plate and the laminate composite backing material. The metal strike face plate or plates has a predetermined defined thickness and has a plurality of slotted holes set at an angle relative to the vertical orientation or axis of the metal strike face plate, or which are straight. The plurality of slotted holes is sufficiently small to prevent the passage of a projectile or fragment therethrough. The laminate composite backing material comprises at least one material selected from an aramid fiber material, S-glass, E-glass, polypropylene and UHMWPE, and is provided in combination with a polymer-based resin material. The optional air space provided between the metal strike face plate and the composite backing material has a depth in the range between 0-12 inches.

A vehicle includes a frame, a front cabin, an armor component, and a retainer. The front cabin is coupled to the frame and selectively repositionable between an in-use position and a maintenance position. The retainer is coupled to the armor component and defines a slot extending laterally across a portion of the retainer. The vehicle is reconfigurable between an A-kit configuration and a B-kit configuration. In the A-kit configuration, the armor component is removed from the vehicle. In the B-kit configuration, the armor component is coupled to the front cabin. The retainer is offset the armor component by a retainer spacer.
