time to address this issue head on ij shield is what i call 3 things in one ( you probally heard that on some electronic but i came up with the idea) its a shield that can extend its defensive range because of the hub in the center wich creates a beam shield ( you'll notice the hub or whatever looks like the beam shield on the arms of ms in V Gundam) also it stores a beam boomerang when stored on the shield it turns the shield into a beam saber shield like providence gundam. so that wraps up the issue of the shield just spreading my knowlege to help my fellow posters (more or less)

edit: in light of new information the hub on the shield maybe a rocket anchor (like sword strike)
