Abstract: Disclosed is an expandable enclosure suitable for a cargo vehicle, a passer vehicle, a stationary shelter or a stationary storage facility. An expansion unit is outwardly translatable from the enclosure by racks fixed to the unit. The expansion unit has first uprights fixed between the racks and second uprights fixed to the enclosure but having a sliding connection with the racks. Third uprights are disposed between the first and second uprights and are slidingly connected between the racks. The expansion unit may be mounted to the enclosure by the gears alone or may additionally be supported by a cantilever beam when the expansion unit is being deployed.

Abstract: A military tank is equipped with an armored box structure in the space nolly occupied by the gun turret. A lid on the box structure is raisable to an inclined position suitable for the firing of a missile carried on the lid undersurface. As the missile is fired an explosive-charged line attached to the missile rear end is drawn out of the box structure onto the terrain (along the missile line-of-flight). By exploding the line charges it is possible to detonate enemy land mines in the vicinity of the charged line.
