OK, so evidently this item has been errata'd WAY more than I thought.
Here's the rules I was running off of:
Here's the current rules, directly out of my brand-new PDF of Tac Ops: Advanced Units and Equipment.
While we use the rules as written, this is the sort of absolutely hammering nerf to an item that's infuriating. Not only is it now less effective at granting speed, but now automatically destroys the Supercharger with
no possibility of repair since it's a 1-slot item. All for absolutely no difference in Battle Value. As with all major rules changes, effective at the beginning of the next contract, the correct rules will be used. So whomever else it was who mounted a supercharger, and I know there's at least 1 of you,
pay attention.
