The Shield is broken into 6 pieces and stacked onto top of each other compacting the disk. It has an arm pad with a spring loaded handle to activate the shield.
It is not as big as a normal shield but can be hidden easier. It is all made of Stygium
Its mainly used by several squad classes: Magic Support, Recon Officer and Strategic Adviser. It is very useful for someone in a tight spot. The shield's activation can be dangerous if something is caught inbetween the plates.
It is based of the Percy Jackson's shield in the Lightning Thief Movie
