We are where we are. The Army's not going to grow and its abandonment of peer- and near-peer capability isn't going to change, either. The Land defence of Europe speaks Polish, various Baltic and Scandinavian languages and US-accented English and we should stop kidding ourselves that two pisspot little brigades with aged-out kit and utterly inadequate fires and AD will/could/should make any difference whatsoever in a major ground war.
We're going to remain firmly in the 'storm ashore and break lots of stuff' and related air assault activities against Mbongo Gorge levels of opposition and we'll probably be quite good at Foreign Internal Defence, training and such, provided we can find a suitable nation with the appetite for our services, but that's about it. The future of the British Army, at least in the short term and absent an existential Land threat, is Toyota Wars - although, one hopes, also without the endless, oozing-sore, pointless and slow-moving, risk-averse patrolling exercise in places where everyone hates us, which so characterised the Noughties and Teens of this century.
The RAF and the Navy, by contrast, are still very much in the peer game and I don't necessarily accept that's a bad strategic posture. It certainly matches our historical strategic approach, which, with the exception of 1914 to 1918 and 1939-1963, has never relied on a mass Land capability,
