An assembly for changing the posture of a weapon coupled to a sensor system comprises a weapon mount configured to support a weapon. The assembly further comprises a movement mechanism coupled between the weapon mount and the sensor system. The movement mechanism is movable between a first configuration in which a boresight or barrel of the weapon is aligned with a first axis of a line of sight of the sensor system and a second configuration in which the barrel of the weapon is disposed along a second axis rotated with respect to the first axis such that the weapon is no longer pointed in the same direction as the sensor.
