– RAND – The role of U.S. special operations forces (SOF) in the Middle East has expanded steadily since the inception of the counter-ISIS campaign in 2014. In part, this expansion is due to the metastasis of ISIS into Libya, Yemen, and other countries beyond its major land-holding presence in Iraq and Syria. But the most notable feature of the expanded U.S. SOF role in the Middle East has been its work alongside indigenous forces in Iraq and Syria. Conventional and coalition forces provide additional numbers of troops. What makes this campaign so unusual is that U.S. forces are not providing the muscle of the frontline combat troops. Instead, the campaign is conducted “by, with, and through” others, a Special Forces phrase that the CENTCOM commander, General Joseph Votel, has adopted to call attention to this new way of warfighting. If the counter-ISIS campaign succeeds in dislodging ISIS from Iraq and Syria, this approach is more likely to be considered for other, similar conflicts.
