If they're really sensible, they'll provide an uplift in manpower numbers for the RN and RAF as well.
Maybe Continental operations are off the agenda beyond trip wire responses on behalf of NATO and overseas training. As a result, maybe the RN (and Lightning Force) gets beefed up (or not cut as much) to provide the Carrier Strike and Littoral Strike Groups, and the assets for the protection for the offshore infrastructure?
