There's a certain strata of people, mostly boomer mongs, who live in this fantasy land where we're still in the Cold War and had five full combat ready divisions, three of which were fully equipped armoured divisions, 1000 combat ready tanks, 900 combat aircraft, 60 combat ready surface warships and 20 submarines. That's why they concoct these fantasies about how the UK military could 'take the fight to Russia' or whatever the fuck. Actual literal medically diagnosable delusion.
The reality is that we have barely a single division with maybe 20-30 tanks, a pitiful number of artillery pieces and rocket/anti-tank weapons with virtually no rounds for either, 150 combat aircraft (on paper, but only a few dozen combat ready), 25 or so warships (constantly docked for maintenance) and currently ZERO active nuclear submarines whose nuclear deterrent has FAILED to launch during both recent tests.
We are officially a third world non-nuclear military power.
