What is one battalion going to do against a determined and sized force from Russia?
Even at the height of the cold war in the 1980s the entire British and NATO defence doctrine essentially rested on sacrificing the British Army in Germany to slow a potential tank advance from Russia to buy diplomats (a maximum of) 24 to 48 hours prior to the deployment of battlefield tactical nuclear weapons.
Which we all know would have escalated rapidly to the larger ICBM variety.
This Battalion in Estonia is purely a demonstration of NATOs intent. It isn’t meant as a force provider or even to provide a strong point with which to resupply into.
Be under no illusion.
If either Russia or China now, decides to roll over the hills and plains of Asia and/or Europe, there is pretty much sweet FA we can do to stop it.
Thoughts contrary to this are singular fantasy.
The real question is why dont they…
Simples, why bother taking large swathes of territory in a huge 19th or 20th Century style invasion when you can simply use newer technologies to achieve your aim of political destabalisation, naturalisation and propaganda far far more effectively.
Or as China is now demonstrating, just pick away at the ‘prize’ parts you want. Oil fields, shipping lanes, etc.
Taking a whole country, means subjegating, controlling and providing for that populace. Else you end up with a Vietnam or Iraq.
