The invention provides systems and devices for an easily replaceable bearing system for a gunner stand of a vehicle. The bearing system reduces vibration from the vehicle on the bearings, decreases wear and tear, and reduces audible rattling. The bearing system includes a shuttle having a backplate and protruding geometry. Biased members are removably attached to the protruding geometry and are configured to create tension on rails of a gunner stand, holding the bearing system within the rails.

An armed aerial platform (100) includes a weapon for firing a projectile from a barrel (102) that defines a weapon axis (104). The weapon is supported by a single-axis gimbal mechanism (116) within a central vertical slot (112) in a rigid body (108) of a UAV (108) carried by a propulsion system (114) including at least four rotary propulsion units. The gimbal mechanism (116) provides an elevation adjustment of the weapon axis (104), while the azimuth adjustment is provided by motion of the UAV (108) itself.

An attachment mechanism is provided for connecting a trunnion shaft to a pivoting platform. The mechanism includes a bracket, a block, a polygonal terminus attached to the trunnion shaft, a pair of bolts and fasteners. The bracket has a center recess and flanking surfaces parallel to the pivoting platform. The block has a cutout notch. The polygonal terminus inserts into a gap formed between the recess and the notch. The pair of bolts extends through the bracket and the terminus, and inserts into the block. The plurality of fasteners attaches the bracket at the facing surfaces to the pivoting platform.

The embodiment of this invention is a combined zoom surveillance camera and zoom scope firearm interconnected on a bipole shaft apparatus, including: A top end ball-bearing which is partially encompassed by one end of a peg brace connected to a rotatable overhead pulley rim; A off-middle tripod of three circular level pivotal surveillance cameras; A off-middle ball-bearing which is partially encompassed by a bearing ring affixed with three hook shaped rods for attachably hanging the bipole shaft apparatus from a ceiling; and, a bottom end base of at least one to three scope firearms for targetting a threatening mass human shooter. The entire bipole shaft apparatus of said top end ball-bearing, off-middle three cameras, off-middle ball-bearing, and bottom end one to three firearms may be simultaneously tilt shifted and circularly rotated on a downward angle whenever a local or distal computer terminal operator activate the necessary electrical wire or wireless torque energy conveyed to the bipole shaft's top end ball-bearing's said connected peg brace and pulley rim band via an electric motor and generator box.
