Abstract: A blast-resistant escape window for an armored combat ground vehicle has a cassette which fits within, and closes, a though-opening in a frame of a windscreen. Two releasable lever-operated locking mechanisms for releasably locking the cassette in the through-opening are mounted on the windscreen at opposite sides of the through-opening. The cassette can to be pushed out of the through-opening when the locking mechanisms have been operated to release the cassette from being locked to the windscreen, thereby providing an alternative exit for personnel in the vehicle.

Abstract: A method of transporting commercial cargoes by truck-tractor/semi-trailer over roadways and by self-propelled/remote-controlled semi-trailer in off-road conditions. The self-propelled semi-trailer can disconnect from its pulling truck-tractor and deliver cargoes through all types of off-road terrains or conditions then reconnect and travel over roadways again. A plurality of permanently mounted stationary and/or retractable axles, with non-steerable wheels attached, are mounted at the rear-section of the self-propelled semi-trailer chassis for supporting it during connected or disconnected operating modes. A retractable axle is permanently mounted ahead of the rearward mounted wheel axles for supporting the weight of the front part of the semi-trailer when it is disconnected from its pulling truck-tractor. The retractable forward mounted axle has steerable wheels at either end for steering the semi-trailer in its disconnected operating mode.
