An interesting take Stobie.
I would add another dimension.
The balance between the armed forces doesn’t reflect your views. The UK is spending around 2% GDP on Defence but too much is going to Army and not enough to Maritime (RAF/RN)
To project power and create worldwide influence and partner with the USN you can’t do it with an Army focused on continental Europe and you can’t do it by underfunding and downgrading the Amphibious forces/Commando.
Even the RAF lacks deployable reach and is balanced toward home defence and seem unwilling to fully embrace RN deployments. (See debate on service conditions for deployed RAF personnel).
Time to wind down the Battle of Britain mentality and once again embrace the Nelsonian spirit.
I was pointing more at the reach the UK still has - we're just out of a ten year air bridge supporting 10K troops in the field for instance - that's something a surprisingly low number of countries can do - and it's why France for instance, turned to the UK for logistics support in Mali when it turned out they didn't quite have the right mix of transports to do the job.
I can't speak the balance between the services (and wouldn't want to, if I were honest) but right now, the there's some stuff the UK does that's still relatively high tier.
As for the Battle of Britain quip, I'm a bit ticked off about that if I were honest - I'm not and never have been a flag waving nationalist - we do some stuff well, could do better on other items and yes, the post Brexit future is either uncertain or unclear, depending on the semantics you're playing on.
I don't think however, there's much of a sense of focus for the Army in Europe these days however - they've spent the last couple of decades in sunnier climes, the bases and commitments in Europe are gone and as I've said, we've not got much in the overall mix that's going to tip the balance in a land war in Europe. We're not sitting in bases, ready to race for the Fulda gap any more and haven't been for decades.
One interesting thing coming out of the later briefings and exercises however does seem to be a renewed interest in one old theatre no-ones been paying attention to for a while - Norway.
We'll see how that shapes up I guess.
The restructuring of the Royal Marines could get interesting I agree (interesting in the sense of the old Chinese curse)
Right now, they're a self contained mini-army with logistics tail and the ability to land anywhere by air or by sea as a light infantry force with some organic artillery etc. The future structure as suggested seems to be to break that into penny packets of SF-lite forces. That effectively takes a formation out from under JCS however so it may be a "to be reviewed" concept.
