Any use for military governor building line?

[MikeV]

I think... if you build the governor's buildings in certain colonial territories (I've noticed it in the US and India), you can't build any other buildings and therefore can only recruit militia; building military governor's buildings means you can recruit a selection of units.

OK, that makes sense: in those regions where we can't build the barracks/armory, etc., it's useful to have the Military one.
