Would not be surprised if US Special Forces are doing much the same.
1. There are US Special Operations personnel present, with the three likely candidates being ACE (Delta Force), DEVGRU (SEAL Team 6), and the Activity (ISA).
2. That 'SAS' missions are typically joint SAS-SBS missions, with some instances of 'SAS' missions being fully SBS missions (eg the hunt for Bin Laden in ToraBora that was a joint SBS and Delta mission, but that the media categorized as a SAS mission).
3. That whoever is there, be they SAS, SBS, Delta, DEVGRU etc, they are absolutely killing professionals.
