US military forces seem poised to take a prominent role in the long-awaited battle to take down Raqqa, Syria, the capital of the self-proclaimed Islamic State.
Though the Pentagon has long downplayed the role of US ground troops in the fight against the ISIS terror group in Iraq and Syria, recent deployments of many more "boots on the ground" suggest they may be front-and-center in the coming months.
Earlier this week, a convoy of US Army Rangers riding in armored Stryker combat vehicles was seen crossing the border into Syria to support Kurdish military forces in Manbij. The convoy, identified by SOFREP as being from 3rd Ranger Battalion of the 75th Ranger Regiment, was the most overt use of US troops in the region thus far.
Until this most recent Ranger deployment, the Pentagon had adamantly stuck to the line that its "regional partners" — Iraqi security forces and Kurdish Peshmerga for the most part — were bearing the brunt of the battle.
But on Wednesday, another curious deployment seemed to counter that narrative. According to The Washington Post, US Marines from the 1st Battalion, 4th Marine regiment had left their ships to establish a combat outpost inside Syria that is apparently within striking distance of Raqqa.
"For the base in Syria to be useful, it must be within about 20 miles of the operations US-backed forces are carrying out," the Post wrote.
The unit, part of the 11th Marine Expeditionary Unit, recently finished conducting training exercises in Oman and Djibouti. Its new outpost inside Syria has M777 Howitzers that fire 155mm projectiles, which are likely guarded by additional infantrymen at the site, according to The Post.

Lt. Gen. Stephen Townsend, the commander of Operation Inherent Resolve, told the Fayetteville Observer last year that most US troops were in Iraq or Kuwait, though "some" were operating inside Syria.
Meanwhile, US special operations forces, who are said to be taking a training and advisory role with Iraqi and Kurdish forces, were quietly given more latitude to call in precision airstrikes and artillery. As the AP reported in February, advisors are now able to call in airstrikes without seeking approval from an operations center in Baghdad.
Additionally, advisors were embedded at lower echelons of Iraqi security forces at the brigade and battalion level, rather than division — meaning that US forces are increasingly getting closer to direct combat.
Though the new directives were lauded by the Pentagon as "adding 'precision' to ground operations," wrote The Institute for the Study of War, "it also underscores that US personnel are increasingly at the frontlines of the operation. Indicators from the new US Administration, including a proposed 10% budget increase for the Department of Defense, suggest that it may expand the level of US involvement in Iraq, beyond the Mosul operation."
A spokesperson for the 11th Marine Expeditionary Unit did not respond to a request for comment.
Col. John Dorrian, a spokesman for OIR, said the moves into Syria were to pre-position US forces so they can provide logistical and fire support to "Syrian partnered forces" who will eventually assault Raqqa.
The Marines and Rangers will provide the "commander greater agility to expedite the destruction of ISIS in Raqqah. The exact numbers and locations of these forces are sensitive in order to protect our forces, but there will be approximately an additional 400 enabling forces deployed for a temporary period to enable our Syrian partnered forces to defeat ISIS," Dorrian told Business Insider.
He added: "The deployment of these additional key enabling capabilities allows the Coalition to provide flexible all weather fire support, training and protection from IEDs, and additional air support to our Syrian partners."
The White House is considering whether to send another 1,000 American soldiers to Kuwait to serve as a "reserve force" for the Raqqa offensive, Reuters reported Wednesday. Officials who spoke with Reuters said there were about 6,000 US troops currently deployed in support of Operation Inherent Resolve, up from the 5,000 that was reported in January.
The presence of additional US ground troops inside Syria — even miles from the frontline — would bring with it considerable risk. Combat outposts often draw rocket and mortar fire, in addition to small arms. Last March, a Marine outpost established to support the operation to retake Mosul, Iraq came under rocket attack by ISIS militants, killing Staff Sgt. Louis Cardin.
A total of nine American service members have been killed in OIR combat operations, while 33 have been wounded, according to Pentagon statistics.
