CIA is predominantly human intelligence, big-picture targeting, and analysis.
But, starting with GWOT, the DIA picked up its own human intelligence. They want it their way, and don't want to play with gatekeepers. The DOD also owns SIGINT via the NSA, which is a military organization headed by an Admiral/General, and they want to be able to pair their existing strengths with HUMINT.
Several NATO countries, esp. the Baltics / Central Europe have been expanding military HUMINT in the same way, esp. in anticipation of Russian infiltration and SF work that was seen in the early days of Ukraine round 2.
In other words, everyone else is doing it, even if it's fragile, expensive, and wasteful.
