Turkish-backed militants drill in northwest of Syria

SNA was formed by combining several militia groups in northwest of Syria in 2017. Due to direct support and supervision of Turkey, the group is famous as TFSA (Turkish-backed Free Syrian Army).
The group itself is not strong in terms of fighting and usually is used to keep the lands occupied by Turkish army in north of Syria.

In the released images of the drill, Turkish flag and armored vehicles can be seen.

Drill by SNA and news that militia groups are preparing in Idlib area can be interpreted as imminent attack of militia against Syrian army in Idlib.
Last week, National Front for Liberation (NFL) group, which is another main group supported by Turkey, drilled and claimed that two batches of the new forces passed the training in special mission.
