You have 20 years in the Navy, right? If so, I am kind of surprised you wouldn’t know at least a 30-second sound byte on it for a DCO interview. But for next time, you can do some self-searching to find out what Navy Intel does. Some ideas:
- ask an IS or Intel O
- read Joint Pub 2-0
- read
https://www.mynavyhr.navy.mil/Caree.../Active-OCM/Information-Warfare/Intelligence/
- read a memoir, e.g. “Knowing the enemy: an intelligence officer's memoir, 1966-2014” by CDR David Muller
- read unclassified intelligence reports that are posted on the websites of ONI, DIA, ODNI, etc.
- listen to podcast episodes with intelligence professional guests, e.g. Jocko, Sean Ryan Show, War College, War on the Rocks, Fighter Pilot Podcast, etc.
