Abstract
A dual-purpose assault ladder and bridging apparatus includes a right frame and a left frame both including upper and lower frame tubes. Assault steps are connected between the right and left frames. Spanning supports connect upper frame tubes. Truss brackets secure one end of an assault step to the frame elements. Assault step support tubes are located to support the assault steps. Bridging steps are connected between the right and left frames and the assault steps. A top portion is mounted at an oblique angle slanting the top portion to position the angled assault steps substantially parallel to the ground when the ladder is leaned against a wall.
