Last time I looked (five minutes ago), the United States Intelligence Community—an agency that exists purely as a coordination/clearinghouse for other intelligence aencies—had 17 member agencies. And those are the DECLARED intelligence agencies. Did you know that the Army of the US Navy (the Marine Corps) has its own intelligence agency? And so does the Coast Guard! https://canada.masto.host/@graydon/113606901593946065
@cstross And? Every significant operational group in every branch of the military in every country that has one has a group of folks doing intelligence — even if the core intelligence function is entirely externalized to a single organization (or more commonly, three, one for domestic, one for foreign, and one for military), those organizations will have intelligence capacity native to the unit, because they need those folks on the ground in the field at all times and they can't do anything without it. The work that all these folks do needs coordination. It's a complicated intelligence structure because it's a massive imperial military.
