WASHINGTON — Over the last week videos and pictures posted by Kurdish activists on social media show flatbed trucks delivering U.S.-made MRAP, M-ATVs, and up-armored bulldozers into Syria.
Military officials say these vehicles are not part of the U-S.-led coalition's aid to Kurdish allies on the ground who are currently engaged in a tense street-by-street urban battle in Raqqa — ISIS’s self-proclaimed capital. The images of heavily armored American vehicles flowing into Syria emerge as the Kurdish fighters attempt to push closer to Raqqa's city center and their progress has slowed in recent days.
"The SDF [Syrian Democratic Forces] has reportedly encountered intensified resistance and 'better-emplaced defenses' over the past four weeks following initial rapid gains in districts on the outskirts of Ar-Raqqa City," according to a report of the latest assessment from the Institute for the Study of War.
Nevertheless, progress continues, according to Navy Capt. Jeff Davis, a Pentagon spokesman.
The American-backed Kurdish fighters in Syria have taken heavy casualties, Davis said. Last week, three westerners, including two Americans who were not active-duty military service members, were killed in what was described as a mine explosion by sources on the ground. In all, Kurdish fighters with the People’s Protection Unit, or YPG, have lost 35 fighters in the month of July alone, according to YPG press releases.

Officials with Operation Inherent Resolve, which oversees American operations in Iraq and Syria, have push backed on claims that progress has slowed or stalled, calling the reports "not true."
"The SDF have not suspended military operations. In fact, over the course of the last week, the SDF have cleared more than 35 [square kilometers] of ISIS-held territory, in and around Raqqa," said the OIR official.
However, the videos of U.S. armored vehicles headed towards the embattled city of Raqqa calls into question the type of aid being delivered to the Kurdish allies and its adequacy to liberate the city from ISIS fighters.
Armored vehicles are a part of coalition aid to the SDF, officials at the Pentagon said. Those vehicles are Guardian armored trucks and U.S. up-armored Humvees, according to officials at OIR.
However, American-made M-ATVs and MRAPs are not included in the aid package for the SDF. Also, pictures of the M-ATVs show mounts for the Common Remotely Operated Weapon Station, or CROWs system — a remotely operated weapons system that can be controlled by troops from inside the vehicle. CROWs systems are also not included in aid to Kurdish fighters. These vehicles have commonly been operated by U.S special operations forces in Syria. The timing and appearance of the large convoys of M-ATVs calls into question their purpose.
When asked by Military Times about whether the U.S. was planning to increase troops in Syria or engage in a more active role beyond advising partner forces, OIR would not confirm or deny, citing operational security.
The clips also show armored bulldozers and earth movers. According to the Defense Department's fiscal year 2018 request for funds for the train-and-equip program for Syrian partner forces, these vehicles are included in aid to "vetted" Syrian groups.
Armored bulldozers have been instrumental in the fight against ISIS in Iraq and especially Mosul where more than 100 Caterpillar D7R dozers have been sent since 2015, according to a report by the Washington Post.
The bulldozers in Iraq were used to help move Iraqi forces block by block in Mosul, while also helping create ad-hoc defenses.
According to the Syrian Observatory for Human Rights — a human rights watchdog reporting on the conflict in Syria — Kurdish forces have entered the Yarmouk district in Raqqa, where clashes are ongoing.
"The Coalition has anticipated the battle to liberate Raqqa will be tough and may take some time," said an official at OIR. However, ISIS fighters in Raqqa "will eventually be defeated… this is certain."
