A rebel blitzkrieg against President Bashar al-Assad’s forces in northwestern Syria reignited that nation’s dormant civil war last week, when a coalition of militant groups united behind Hayat Tahrir al-Sham — a former Al Qaeda affiliate known as the Al Nusra Front that the U.S. considers a terrorist group — and captured Syria’s largest city, Aleppo. The rebel army, which include Turkish-backed forces, have since pushed government troops out of Hama, another major metropolis.

For years, Syria’s complicated battlefields have been populated by shifting groups of militants battling a range of enemies, including each other, and proxies backed by outside powers. Iran and Russia have propped up the autocratic Assad regime for more than a decade, while Turkey and the United States have troops on the ground in areas outside government control, and each support local proxies.

News reports and videos posted on social media indicate U.S.-backed rebels, supported by American airstrikes, may now be battling Syrian government forces as part of renewed fighting in the east.

That U.S. backing means boots on the ground. Around 900 U.S. troops are deployed in Syria alongside private military contractors, in what one expert calls “arguably the most expansive abuse” of the war powers granted to the executive branch in the wake of 9/11 — and those troops have, on average, come under fire multiple times each week since last October, according to new Pentagon statistics obtained by The Intercept.

Since the war in Gaza began last year, U.S. forces have been under sustained attack by Iran-backed militants across the Middle East, with the Pentagon’s Syrian bases being the hardest hit. Since October 18, 2023, there have been at least 127 attacks on U.S. forces in Syria, according to Lt. Cmdr. Patricia Kreuzberger, a Pentagon spokesperson, and information supplied by U.S. Central Command, or CENTCOM. On average, that’s about one attack every three days.

“Why are U.S. troops in Syria? What is the mission? What is the endgame? And is this legally authorized?”

Mission Support Site Conoco — also known as Mission Support Site Euphrates — located near a gas field in northeastern Syria, has been attacked about 40 times since last October, according to a “defense official” who would only agree to speak on background using that moniker.

Another Pentagon source confirmed that several U.S. troops are currently being evaluated for potential traumatic brain injuries after incoming mortar rounds landed near that base in eastern Deir Ezzor on Tuesday.

Documents provided by another Pentagon official, on the condition of anonymity, show that still another U.S. base, Mission Support Site Green Village, has been attacked at least 28 times. Last month, U.S. troops came under rocket attack at Patrol Base Shaddadi, one of at least 22 attacks on the small outpost since last October. There have also been at least 11 attacks on al-Tanf, a small garrison near the Iraq and Jordanian borders in southeast Syria.
