Apparently, you didn't read the article very closely. It specifically mentioned how many men were there, where they were, how they were dressed, what types and color vehicles they were using, and mentioned where they were receiving air drops. The article might as well have painted a target on them. Perhaps you've forgotten, but bin Laden put out a bounty on American military men. That article provided far too much specific information.

That's a far cry from saying "There are 4 teams in Afghanistan" since that country is about the size of Texas. I take it you've never served in the military. One of the things they stressed to us was the need for operational security. Even simple and unclassified pieces of data can reveal a lot about military operations. The Viet Cong were masters at putting together info on our operations. Nothing I've seen indicates the Afghanis aren't capable of doing the same.
