Ok, just for grins after seeing this post, I did a quick search for threads (not even the ones that are deleted, the active ones) that mention Opsec...
There are 54. Threads - I don't even want to count the posts.
5 are stickies or reminders (like this thread) that warn of the dangers..
there are 49 threads where it is mentioned in some other context, mostly from my spot checking, that it has been violated in some way.
Get your heads out of your 4th points of contact, people... this is not a new issue, and there are a number of you that have been spot corrected for the same types of security violations more than once, twice or three times.
The BGs are cruising the 'net, this board and others like it... as is the US Gov't - mil., intel, and justice...
Think about what you say, and if you are a member of this board - being a civilian, or a foreign national, or young --- is no excuse, it is out there when you sign up, clearly. If you have a question about a post - ask a mod, or a senior member of the board, you might get scalded - but it's better than being incinerated if you post a violation.
:2c: rant over, for now - I hope I don't have to post this again - PB might ban me for forgetting I'm not a mod anymore.
