A remote US special-operations base in the Syrian desert is caught in a shadow war between military powers in the Middle East.
Al-Tanf garrison, a US base typically housing between 100 and 200 US troops alongside coalition forces, has for years been a hub for operations against ISIS as well as Iran and its proxies. In August and September, the outpost was involved in a series of attacks, including a rocket attack by Iranian-backed militias that wounded three US troops.
