Although it's an old video from 2013 it's still relevant for today in seeing how the 'moderates' are allies with Isis.

With news reports on Wednesday leading with statements like “online.wsj.com/article/SB10001424127887323420604578652250872” — even as the Free Syrian Army and the Syrian National Coalition congratulated FSA fighters for their capture of the Menagh Airbase — we look at which groups were involved in the assault.

Did Islamists Lead The Operation?Islamists, particularly from the Islamic State of Iraq and as-Sham, were heavily involved in the assault on the airbase — activists associated with them posting large quantities of footage showing their role.

However, the biggest clue as to their relationship with the Free Syrian Army may be in this video, posted on Monday immediately after Menagh fell. In it, the FSA head of the Aleppo Military Council, Abdul Jabbar al-Oqaidi, leads a press statement praising his fighters for taking the base. Standing next to him is ISIS Emir Abu Jandal, whom al-Oqaidi invites to give a statement.

The footage indicates that not only are there links between ISIS and FSA fighters on the ground, but that there was a high level of coordination and collaboration in the operation to besiege and take the airbase.
