"The US forces currently operating at Rmeilan might include US Air Force Special Tactics Squadron operators, such as combat controllers, pararescue jumpers and special operations weathermen," Majumdar suggests in his article.
"Special tactics squadron airmen — particularly combat controllers — are often embedded with US Army Special Forces and US Navy SEAL units. The aforementioned helicopters could be from the US Army's 160th Special Operations Aviation Regiment — which is an elite unit tasked specifically to support top tier special operations units," the journalist underscores.
The London-based SOHR is not the only source reporting on the US maintaining control over the Rmeilan airbase.
On January 20, Diana Al Rifai of Al Jazeera reported that the US troops have been deployed at Rmeilan airfield to support Kurdish fighters against Daesh (Islamic State/ISIL), quoting the opposition Syrian Democratic Forces (SDF) spokesperson Taj Kordsh.

"Under a deal with the YPG, the US was given control of the airport. The purpose of this deal is to back up the SDF, by providing weapons and an airbase for US warplanes," the SDF spokesperson said.
On January 22, however, a spokesman of the United States Central Command (CENTCOM) "denied that US forces have taken control of any airfield in Syria" in an interview with Al Jazeera.
Curiously, on the same day Stratfor, a geopolitical intelligence firm usually referred to as the "shadow CIA," released low resolution satellite imagery taken on December 28. The images show construction underway at the Rmeilan airfield.

"Before the war, the airfield was an agricultural airstrip used by the Syrian government. As such, its runway was only 2,300 feet (700 meters) long, a length that appears to be doubling," Stratfor's report elaborates.
"The US involvement in al-Hasaka province would not be so unusual; the United States nearly always attempts to establish an air bridge to support the semi-permanent positions of the conflicts in which it operates," Stratfor's analysts emphasize.
Although the Pentagon has denied the reports regarding the US Special Ops deployed at Rmeilan, it is known that about fifty US military troops have been operating in Syria since December.
Though, theoretically, their role is limited to training and advising the so-called Syrian opposition forces on the ground, American Special Ops have also been directly involved in combat operations in the region, Majumdar stresses.
"That raises the specter of the US special operations forces facing another Black Hawk Down moment in Syria," the journalist warns, referring to 1993's Operation Gothic Serpent in Somalia when US Army Rangers were caught in a massive ambush.
"As US special operations forces step up their activity in Syria — the isolated American forces face even greater risks than their forbears," he underscores.
