I can recruit colonial divisions to save manpower.their troops get combat bonuses within the country.I can control their army myself or let them do it.they gain full access to the building slots and manpower, eventually building an army.I can't build radar or rocket silos there unless they research it too.I don't gain direct access to the single building slot there when researching Concentrated/Dispersed Industry V (1943 tech).Let's say I'm playing France and consider releasing Laos When I play (single player) any of the major countries that have releasable nations, one of the first things I decide is which of them to release.
