Abstract: A split hatch with armored hatch leaves that are positioned to shield occupants standings in the hatch opening when the hatch is opened. The hatch leaves can be fixed at different angles to provide improve protection from different threats. The armored hatch leafs are oversized to engage the hatch opening in an overlapping configuration to prevent passage of nuclear, biological or chemical contaminants from entering the vehicle between the leaves and the edge of the hatch opening. A seal assembly overlaps the edges of the leaves to prevent contaminants from entering the vehicle between the leaves themselves.
