Abstract: A vehicle hatch system includes, a frame defining a perimeter of a hatch that is releasably attachable to a hatchway of a vehicle, at least one sub-frame attached to the frame configured to allow replaceable panels to be attached to the at least one sub-frame and the frame, at least one transparent non-armor panel is replaceably attachable to the at least one sub-frame and the frame, and at least one armor panel that is replaceably attachable to the at least one sub-frame and the frame.

Abstract: A positionally releasable vehicle armor arrangement includes, at least one plate positioned proximate a hatch of a hatchway of a vehicle configured to shield an occupant of the vehicle from projectiles, at least one retainer in operable communication with the at least one plate configured to structurally maintain position of the at least one plate relative to the vehicle separately from the hatch, and a release in operable communication with the at least one retainer configured to defeat the structural positioning of the at least one plate maintained by the at least one retainer so that the at least one plate can be repositioned sufficiently to avoid obstructing egress through the hatchway.
