US forces and US-backed militant groups deployed in the Syrian border area of At-Tanf have reportedly carried live-fire drills involving a M142 HIMARS (High Mobility Artillery Rocket System). The video, which allegedly shows a part of the drills, appeared on YouTube on January 3, 2019. However, it remains unclear when it was filmed.
If the development is confirmed, this will be another confirmation that the announced withdrawal of US troops from Syria does not mean that the US is really going to withdraw all of its forces from the country.
