The Brute Wrecker has a natural AR stat of 20, and is available to the Scavengers subfaction. As a non-character model, it is eligible for tokens via Scavengers of the Wastes. If a wrecker has one or more scavenge tokens, does its AR go to 21 or higher?

I would assume a natural AR of 20 still fails, but the implication is that even with modifiers a wrecker or other model with a high AR can reach AR stats over 20 before modifiers are applied.
