yep. The military standardised on kilometers because NATO did that.

And NATO includes a lot of countries that use the metric system. And
goes on foreign expeditions.

It hadn't gone on any at the time it went to kilometres.

So I was right.

Nope, wrong, as always.

OK. So what is the real reason that "the military" (in which country -
worldwide?) adopted the metric system?

As I said, so NATO worked better. That was the reason for
standardising on other stuff like ammo too, for the same reason.

Is it related to the fact that (UK) Ordnance Survey maps (originally
linked to the British army) adopted a National Grid that used kilometre
(rather than mile) squares measured from some datum off south-west
England - even for its imperial-scale 1-inch and 6-inch maps, long before
OS changed to 1:50,000, 1:25,000 etc maps (2 cm = 1 km).

Partly.

Is there some common factor that caused both military and OS (and NATO) to
use kilometres?

Forget the detail there.
