Just weeks after President Trump ordered the withdrawal of U.S. forces from Northern Syria, troops have returned to defend oil facilities from falling into the hands of the Islamic State. There were approximately 1,000 American troops in Northern Syria when President Trump announced, “It’s time to come back home,” earlier in October, but with this new deployment, American troop counts in the war-torn country are once again at around 700.

The 500 additional soldiers, along with M2A2 Bradley Fighting Vehicles, hail from the National Guard’s 30th Armored Brigade Combat Team, and will continue to partner with Kurdish forces in the region “to defeat ISIS remnants, protect critical infrastructure, and deny ISIS access to revenue sources,” according to Col. Myles Caggins on Twitter.
