National governments deal in both intelligence and military special operations functions that either should be completely secret, or simply cannot be linked to the sponsor. It is a continuing and unsolved question for governments whether clandestine intelligence collection and covert action should be under the same agency. The arguments for doing so include having centralized functions for monitoring covert action and clandestine HUMINT and making sure they do not conflict, as well as avoiding duplication in common services such as cover identity support, counterespionage, and secret communications. The arguments against doing so suggest that the management of the two activities takes a quite different mindset and skills, in part because clandestine collection almost always is on a slower timeline than covert action.
