> What is the practical requirement for a world-class tactical unit (or near that level, e.g. D1 basketball or a bad pro team)? I wouldn't expect current militias to be at that level, but what about less developed nation-states?

One common form of US military aid is training elite units in partner militaries, often in less developed countries. This has an evil history, training death squads and other war criminals, knowingly or unknowingly. It also has a cost-effective and good history, training Ukraine's elite units, for example.

(My impression is that it's a cost-effective compromise solution to a very difficult, expensive problem: The institutions of militaries are sometimes highly corrupt and incompetent; the Afghan military is an example. Fixing that problem would require building a new military, which could take 20 years at great cost and may be impossible: The corruption usually comes from the government, whose corruption comes from elites and from society-wide political problems.)

You can find some competent people and create a small, isolated organization, and train and equip them, and do it cost-effectively. The Afghan military was hopeless; their elite units were reportedly very good.
