Abstract of the Disclosure An armored vehicle is provided with a gun mounted upon its top dock which gun is capable of rota- tion through 360° about a vertical axis. The gun is also simultaneously elevatable through an angle of about 70°. Located upon the deck are a plurality of barriers (some fixed and some conditional, e.g., opened hatches) which the gun must avoid during its rotational movement The apparatus of the present invention includes a programmable read-only-memory which stores the location and height of each of the barriers on the dock A computer continuously checks the position of the gun against the location of each of these barriers and pro- vides signals which prevents the gun from moving into forbidden zones which include the locations of these barriers. As the gun approaches any of the barriers a signal is generated which causes the gun to be elevated from its normal path (if necessary) and lifted over the barriers. The distance from the barrier at which the upward movement of the gun starts is determined by the speed of movement of the gun, the elevation of the gun, and the height of the barrier. Thus, if the gun is moving slowly and the barrier is relatively low the gun can be moved very close to the barrier before any lift- ing of the gun occurs. If the gun is moving more rapid- ly, or if the barrier is relatively high, the upward movement of the gun is started at a greater distance from the barrier so that the gun can be lifted over the barrier without inhibiting the horizontal rotational movement of the gun. The apparatus includes means for -1a- inhibiting the firing of the gun when the gun control system takes over. -1b-
