Great point. What was your assessment of UKR ability to resist an invasion by a superior(non-peer) force? So how are they accomplishing that? Because this stand-alone, vacuum analysis of one nations pacing item isn't a metric that means anything. It's the entirety of western Europe supporting them. What is the scenario that has the UK toe-to-toe'ing it with a peer nation all by themselves? Your metric only has merit in a fantastical scenario. In reality, and certainly as we speak, modern warfare seems to be a coalition approach to maintaining the western worlds culture of rules based order. And the Brits are taking a leadership role in that.
Also, "peer-to-peer" isn't synonymous with land maneuver warfare or LSCO. Peer-to-peer can happen in global competition, low-intensity, and by proxy. A conventional Army guy probably thinks that way tho so I can understand why this is your outlook.
