Sometimes there is no choice. Whether it’s fanatical terrorists, implacable enemies, there are times, in the words of General Stanley McCrystal, when you are dealing with “irreconcilables.” Then, you just have to go in and kill them. That’s when you call upon the elite Special Forces units. Some are world famous - the SAS and the Navy Seals. Others lurk more in the shadows – like India’s Black Cats and Russia’s Alfa Group. But this is deeply high-risk stuff.

When a Special Forces Operation goes wrong, there can be many innocent casualties and profound political consequences. Ask Jimmy Carter. A botched raid cost him his presidency. This series will reveal the workings of these elite Black Ops units and tell the inside story of some of the most dramatic events in recent history.
