Amir-Ali Arasteh, the deputy coordinator of the Iranian Army's Ground Forces, told Tasnim news agency on Monday that the Iranian commandos, from Brigade 65 of the Forces, had took on a mission of advising Syrian forces.
Iran maintains military advisers in Syria, where the regime of Syrian President Bashar al-Assad is engaged in a protracted civil war against various militant forces, including, but not limited to, those of the Daesh group and the Nusra Front.
The Iranian advisory presence comes as part of defense agreements reached between the governments of Iran and Syria. Iran does not have boots on the ground in the Arab country.
Russia, another staunch ally of the Syrian regime, has been conducting an aerial campaign against fighters in Syria since September 2015.
With allied help, the Syrian government has been able to take back militant-held areas, including most recently the ancient city of Palmyra, which had been run over by Daesh back in May 2015.
