I'm not in the military and the closest I've been to anyone in the military was going to the base to catch babies for Operation Special Delivery. I'm watching videos and reading posts and reading context clues but somethings are....still WAY too much to figure out their exact meaning.
MAGs (in referrence to groups/teams)
Opsec (Poster was talking about storing gear)
BDB ("aptly pointed out in yesterday's BDB, we have a clearer, more urgent understanding")
These are what I've came upon and I've heard others on the videos (sometimes it's like listening to gibberish) but if you have any other to share that are common or 'if you hear this brace yerself' as I continue reading through I'd appreciate the knowledge.
