Spook mission

Spook Mission

 Union military jargon for a clandestine, intelligence or recon mission.

Such a mission is usually conducted by NAVINT or ordered to be executed by NAVINT.

The word “spooks” is an old Pre Astro Terran term for intelligence personnel.

It stems from the fact that operatives of intelligence organizations usually work in the shadows and rarely come into the open and their actions and missions are ghostly and shadowy, in other words spooky.
