Coworker is former SF and Private security (mercenary) contractor. He said the CIA is super sketchy but before he retired he was recruited by the NSA “security team”. He said these guys are very secretive and mostly unknown but they have a weirdly difficult selection process(as in they test uncommon skills) and get the best training and gear. Their primary mission set is executive protection and counterterrorism but can operate anywhere and for anyone. If patriots control the NSA then these guys have been doing gods work the past 4 years
