Abstract: An arrangement is provided to protect the occupants of a military vehicle in the event of a percussive-type impact on a surface of the vehicle, such as a mine explosion below the vehicle. The arrangement includes a foot floor supported at a spacing from a respective portion of the interior surface of the cabin which is intermediate the foot floor and the travel surface on which the vehicle is traveling. No structures connect the foot floor and the interior surface of the cabin to one another with a rigidity sufficient to transmit to the foot floor more than a negligible amount of the energy of a deflection of the interior of the cabin in the event that a percussive-type event such as amine explosion causes the interior cabin surface to deflect.
