Abstract : A tank gunner obscuration device is provided for automatically and selectively obscuring the view out of the tank seen by the gunner in response to the firing of the main gun of the tank so as to simulate the obscuration produced by smoke, heat and debris during an actual firing. The device comprises a movable shutter which is automatically pivoted between a blocking and unblocking position responsive to firing of the main gun. The control mechanism for the shutter includes an operating solenoid energized by an electrical timer which controls the duration of the obscuration provided. A series of replaceable panels, which are removably mounted in the shutter frame and provide different degrees of opacity, enable the amount of obscuration to be varied. (Author)
