Abstract: A method for laying a military bridge over an obstacle in a combat zone with using at least one laying vehicle. First, the bridge is loaded on a self-propelled, unmanned, remote-controlled laying vehicle and transported to the edge of the combat zone by water, air, rail, and/or road. From this point, the laying vehicle with the bridge is guided by a manned pilot vehicle to the vicinity of the obstacle. The laying vehicle then begins an automatic slow approach to the obstacle, for which purpose the laying vehicle has a suitable optical system or a laser scanner. At the edge of the obstacle, the topographical situation is scanned. On the basis of the scanner data, the laying operation is simulated, taking into consideration the predetermined design limits. On the basis of the simulation results, a decision is made about whether the laying operation will be carried out or broken off. This decision is then executed.
