It was reported in the media FWIW they were rescuing another elite special ops force (The Army Rangers) If you read this article it implies that the Rangers may not of been in need or in dire straits? It is just strange. The best of the best rarely fail but it is war. It is very difficult to comment on; as these things much less the names of the dead and details of Op’s are generally not in the news. With Obama as POTUS they have been.
One thing I wasn’t sure of. Did the choppers exfil the SEALS by the same route they engressed? This would be a major break of protocol if so. If not, then, as others here have suspected, one of the Afghan national guys gave them up.
