>the status of the Geneva Conventions—were a soldier operating under false identity to be captured by an enemy This is not too problematic. Geneva convention and Hauge regulations are clear. They don't get the protection of Geneva conventions like troops normally are. They are spies or saboteurs. In Russia KGB and now FSB have always been a military service. Captured KGB/FSB officers (in civilian clothing) are not treated as captured military.
