What event, person, place, or thing affects military intelligence history today?

If it's for an assignment, maybe the Enigma Machine and the process of cracking codes? A lot of the process is still in use today, I think the last Enigma code from WWII was cracked a couple years ago.

I would go with cyber SSG (Join to see). The cyber domain is an evolving arena that requires an ever changing and adaptable intelligence package to counter and/or defeat. Cyber covers a very broad area, but in my opinion, how we counter this threat now and in the future will be the means that history will judge the military intelligence profession.

I would say satellites. That has allowed nations to collect information on things we could not have done before without placing our pilots at great risk. Perhaps next to that, I would add UAVs since those are even down to company level now.
