British Army force structure (future proposal)

 

THE BRITISH ARMY'S DILEMMA
✅I expect each of Britain's two Regular Army divisions to look something like the diagram below.
✅3rd (UK) Division will be a tracked manoeuvre force with three brigades. 1st (UK) Division will be a wheeled expeditionary force, also with three… pic.twitter.com/rUkmUaD70V

I continue to find it amazing that even Nicolas' Army Force Structure diagram is a best case scenario for that unit. I am further amazed that even with this optimization, the US Marine Corps outnumbers it. Not gonna bother to look it up but I would bet that Marine Air is bigger than their Naval Air Force. While I view the current force structure of the Marine Corps to be a shell of its former self, I have to remember that size wise its freaking huge compared to many other forces around the world.

First I look at the Brits.

Would it be wise for them to prioritize their naval forces at the expense of their Army?  Considering its an island nation, out of area operations should be their bread and butter.  At least I think so.  If you disagree then should they prioritize their Army at the expense of its Navy so that they can properly reinforce NATO?  What about their Air Force.  It seems to be trying to walk the line between the two with a slight nod toward the NATO mission.  Which way should they go?

Second I look at the US military.

How much is too much.  Does the China threat actually need a large army?  Could we or should we prioritize the Navy over the Army?  We too are an island nation of sorts.  Should the Navy be our number one concern?  Should we revamp our nuclear mission to be able to hold our competitors at bay from attacks on the homeland?  How much should we contribute to the defense of others?  Obviously our armed forces are over the top to protect our own country.  Should we downsize to that level and let others fend for themselves?
