The U.S. military announced on Friday that it is deploying a small number of Bradley armored vehicles, Sentinel radar equipment, and about 100 additional troops to northeastern Syria.

The redeployment is meant to strengthen and protect the U.S.-led coalition, including the Syrian Democratic Forces (SDF), which is fighting ISIS.

The move, coupled with the increased frequency of fighter jet patrols over U.S. forces in Syria, is also designed as a show of presence and a deterrent against further Russian military moves in the coalition’s area of operations. This was highlighted by U.S. Central Command (CENTCOM) spokesman Navy Capt. Bill Urban.

“These actions are a clear demonstration of U.S. resolve to defend Coalition forces in the [Eastern Syria Security Area] and to ensure that they are able to continue their Defeat-ISIS mission without interference,” Urban said in a statement. “The Defense Department has previously deployed Bradleys to northeast Syria pursuant to these goals.”

“The United States does not seek conflict with any other nation in Syria, but will defend Coalition forces if necessary,” Urban added.

The additional troops will include six Bradley Fighting Vehicles and about 100 soldiers from the 2nd Brigade, 1st Armored Division from Fort Bliss, Texas. They will be deployed in support of “Operation Spartan Shield” and will operate in northeast Syria on a 90-day deployment. The Sentinel radar system will be used to help detect and counter enemy drones and missiles.

The U.S.-led coalition “plans to position mechanized infantry units, including Bradley Fighting Vehicles, to Syria to ensure the protection of Coalition forces and preserve their freedom of movement so they may continue [to] defeat Daesh (ISIS) operations safely,” Col. Wayne Marotto, a spokesman for the coalition, said in a statement.

The U.S. had deployed Bradley Fighting Vehicles from the 30th Armored Brigade Combat Team to Syria in October 2019. It later withdrew them later when planned joint patrols with Turkish units never materialized.
