Mk. 1, note the ring handle is attached to shield body with two bolts along the central horizontal axis.
Mk. 2, the bolt attachment has now been replaced with a moulded fitting built into the redesigned chassis. The advantage of this is that the point of excessive pressure beneath the officers elbow (resulting from the bolt attachment) has now been removed.
Mk.3, the hoop handle from the Mk. 2 has been engineered to allow for expansion so that it offers a more versatile fit for different arm sizes. The fixed handle has also been redesigned and now forms a moulded part of the chassis.
Mk. 3 (folding handle), the hoop handle is inherited from the Mk. 2, however the fixed handle on the Mk. 2 has been re-engineered to include the option of being folded flat to the chassis. This is of benefit to logistics as the depth of the shield is now reduced, hence more shields can be stacked within a small space.
Common to both Mk. 3 designs is a re-engineered chassis that removes the foam cushion as the energy absorbing layer, this improves the performance of the shield.
