Backstory on the video:

A cold and wet day. I was not there. This footage off the body of an ISIS fighter by a YPG fighter, a member of one of YPG’s Kobani Canton based units. The footage was then taken and shown in several meetings to reveal the shortcomings of the YPG’s own defences.

What happened?

This part of the video shows the end of the battle of Ayn-Isa, where ISIS fighters realise that the Cemsid Kobani’s Supra-Haraketli Tabur, originally based out of Tal Abyad, is coming for them. The unit that is attacking the ISIS fighter’s position is a unit based out of Kobani Canton who is supporting the counter-attack led by the YPG’s main “quick-reaction force” at the time.

On the 4th of January, 2016, a large ISIS attack of around 100 fighters surged through the country-side of North Raqqa. The ISIS attack immediately overwhelmed three YPG outposts. ISIS fighters then moved around the eastern-flank of the YPG fighters when Arabs from the Liwa al-Tahrir, at the time a YPG-aligned unit, evaporated at the fae of a column of ISIS fighters.

This video is the result of this flanking attack, followed by a short-morning of American airstrikes not seen in the video, followed by rain and clouds that prevented American airstrikes, followed by the original counter-attack that pushed ISIS back the original YPG-line, followed by what’s shown in the video of a unit then breaking the back of ISIS unit as it is flanked on its right (not shown), and attacked in the center (shown).
