A Syrian Arab Army heavy machine gun position in Idlib gets caught out by members of the National Front for the Liberation of Syria. They establish a recoilless rifle position, and let loose a round into the HMG.

For context, this footage was recorded on August 4, 2021 by members of the National Front for the Liberation of Syria. This group, also known as the NFL (no relation), was founded in May of 2018 when eleven rebel faction came together with the support of the Turkish Government. Since their inception, they have undergone a number of leadership changes, ranging from battlefield promotions causing shifts inside of the groups chain of command, to more recently a leader stepping down due to Turkish influence because of embezzlement scandal.

What you're seeing here is members of the NFL establishing a position for a recoilless rifle, identifying a legitimate military target in the form of a heavy machine gun, and then the elimination of said heavy machine gun using the recoilless rifle. All of this happened inside of the city of Idlib.
