A weapon station apparatus comprising: a pedestal adapted to be mounted on an armored vehicle for rotation relative to the armored vehicle about an azimuth axis, the pedestal including a first attachment interface and a second attachment interface laterally-spaced from the first attachment interface; a first spacer including a bottom end configured for removable mounting on the first attachment interface of the pedestal and a top end having a yoke arm attachment interface; a second spacer including a bottom end configured for removable mounting on the second attachment interface of the pedestal and a top end having a yoke arm attachment interface; a driver elevation yoke arm configured for removable mounting on the first attachment interface of the pedestal and for removable mounting on the yoke arm attachment interface of the first spacer; a follower elevation yoke arm configured for removable mounting on the second attachment interface of the pedestal and for removable mounting on the yoke arm attachment interface of the second spacer; and a first elevation rotary bearing supported by the driver elevation yoke arm and a second elevation rotary bearing supported by the follower elevation yoke arm, wherein the first and second elevation rotary bearings (46A, 46B) define a rotational elevation axis; wherein the first spacer is selectably installable between the pedestal and the driver elevation yoke arm and the second spacer is selectably installable between the pedestal and the follower elevation yoke arm to change a height of the rotational elevation axis above the pedestal; characterized in that each of the first and second attachment interfaces defines a plurality of selectable attachment positions, whereby a longitudinal position of the rotational elevation axis is adjustable. a pedestal adapted to be mounted on an armored vehicle for rotation relative to the armored vehicle about an azimuth axis, the pedestal including a first attachment interface and a second attachment interface laterally-spaced from the first attachment interface; a first spacer including a bottom end configured for removable mounting on the first attachment interface of the pedestal and a top end having a yoke arm attachment interface; a second spacer including a bottom end configured for removable mounting on the second attachment interface of the pedestal and a top end having a yoke arm attachment interface; a driver elevation yoke arm configured for removable mounting on the first attachment interface of the pedestal and for removable mounting on the yoke arm attachment interface of the first spacer; a follower elevation yoke arm configured for removable mounting on the second attachment interface of the pedestal and for removable mounting on the yoke arm attachment interface of the second spacer; and a first elevation rotary bearing supported by the driver elevation yoke arm and a second elevation rotary bearing supported by the follower elevation yoke arm, wherein the first and second elevation rotary bearings (46A, 46B) define a rotational elevation axis; wherein the first spacer is selectably installable between the pedestal and the driver elevation yoke arm and the second spacer is selectably installable between the pedestal and the follower elevation yoke arm to change a height of the rotational elevation axis above the pedestal; characterized in that each of the first and second attachment interfaces defines a plurality of selectable attachment positions, whereby a longitudinal position of the rotational elevation axis is adjustable.
