Abstract: A convertible ramp system facilitates transfer of personnel between spaced elevations. The ramp system includes a deck assembly, a convertible main ramp, and a convertible extension ramp. The convertible main ramp has a proximal end hinged to the deck assembly and a distal end adapted for being mechanically lifted and lowered relative to the deck assembly. Both the main ramp and the extension ramp incorporates an adjustable frame assembly and a series of simultaneously articulating foot treads carried by the frame assembly. The ramps are selectively convertible between a stairway configuration and a substantially flat and continuous runway configuration.

Abstract: A convertible folding ladder incorporates first and second rigid ladder sections, each comprising opposing spaced apart longitudinal rails, a plurality of spaced apart rungs between the rails, and a connector plate formed with one end of at least one of the longitudinal rails. Each connector plate of the first ladder section defines at least three spaced apart pin holes adapted for being selectively aligned with pin holes defined by the connector plate of the second ladder section. First and second fastener pins are adapted for being removably inserted through the aligned pin holes, such that the ladder is convertible between multiple different configurations.

Abstract: A modular floatable dock section comprises a fluid bladder having substantially flat top and bottom surfaces, and a perimeter around the top and bottom surfaces. The fluid bladder is designed for being selectively inflated in a deployed condition and deflated (collapsed) for transport and storage. A generally rigid continuous-surface deck is mounted adjacent the top surface of the fluid bladder, and defines a deck perimeter substantially coincident with the perimeter of the fluid bladder.

Abstract: A tactical vehicle incorporates a line deployment tower adapted for use by personnel transferring between an elevated location on the vehicle and a remote target location. The line deployment tower includes a base mounted to the vehicle at the elevated location. An elongated line boom has a proximal end attached to the base, and an opposite distal end. A flexible line is secured to the distal end of the line boom, and is adapted for extending downward from the elevated location when deployed.

Abstract: A deck deployment system is adapted to facilitate transfer of personnel between spaced elevations. The deck deployment system includes a deck defining a substantially flat and continuous deck surface for supporting personnel. A convertible stairway is hinged to the deck and adapted for movement between a stowed condition and a deployed condition. The convertible stairway includes an adjustable frame assembly and a series of articulating horizontally-disposed foot treads carried by the frame assembly. The foot treads remain substantially horizontal upon movement of the stairway between the stowed condition and the deployed condition. When the stairway is in the stowed condition, the foot treads integrate with the deck to form a substantially flat and continuous portion of the deck surface. When the stairway is in the deployed condition, the foot treads cooperate to form steps extending from the deck to an elevation spaced from the deck surface.

Abstract: A vehicle-mounted personnel access platform assembly is designed for mounting on a tactical vehicle. The platform assembly includes at least one mounting brace, and at least one access platform carried by the mounting brace. The access platform defines a raised horizontal surface for supporting personnel at an elevated location adjacent a body of the tactical vehicle. A protective wall adjacent the access platform is adapted for residing a spaced distance from the body of the tactical vehicle to protect personnel staged on the access platform.

Abstract: A convertible ballistic structure has a threat side and a protected side. The ballistic structure includes a body panel assembly, and at least one movable side panel assembly adjacent the body panel assembly. Means are provided for articulating the side panel assembly relative to the body panel assembly, whereby the ballistic structure is convertible between a contracted condition and an expanded condition. In the contracted condition, the side panel assembly extends rearwardly from the body panel assembly and outwardly from the protected side of the ballistic structure. In the expanded condition, the side panel assembly extends outwardly substantially coplanar to the body panel assembly.

Abstract: A modular ballistic wall assembly incorporates a rigid frame including first and second spaced-apart uprights, and at least one cross-member extending between the uprights. A plurality of ballistic panels are carried by the frame between the first and second uprights. Each ballistic panel has top and bottom edges, opposing side edges, and opposing major surfaces. The major surfaces define respective threat and lee sides of the panel. The ballistic panels are arranged edge-to-edge, such that adjacent panels form an unprotected seam therebetween. A first ballistic seam protector is carried by the cross-member of the frame, and covers the unprotected seam on the threat-side of the ballistic panels. A second ballistic seam protector is carried by one of the first and second uprights of the frame on the threat-side of the ballistic panels. The second ballistic seam protector is adapted for covering a second unprotected seam formed between adjacent ballistic panels.

Abstract: A ballistic shield may include a first ballistic plate that includes a ballistic material. A second ballistic plate may also include the ballistic material. The second ballistic plate may be connected to a side of the first ballistic plate so that the first ballistic plate and the second ballistic plate may fold together to substantially overlap. A gap may exist between the first ballistic plate and the second ballistic plate when not folded together. An overlapping ballistic section may include the ballistic material. The overlapping ballistic section may be connected to the first ballistic plate and/or the second ballistic plate so that the overlapping ballistic section covers the gap between the first ballistic plate and the second ballistic plate.
