Since the UN report into the August 21st sarin attack confirmed the use of a previously unknown munition in the attack, which I had previously named the UMLACA (more details here ), there's been a lot of debate about whether or not the Syrian army has such a munition. There's been multiple videos of the munitions posted online by the Syrian opposition, and they've been consistently described as being fired by Syrian government forces. From those videos, I've been able to identify at least two types of these munitions, one type linked to the August 21st sarin attack and past alleged chemical attacks, and a second, high explosive, type.The following video from Daraya, Damascus, published on Decemeber 29th 2012, was highlighted by @hesbol on a blog post attempting to discern the range of the UMLACA. It shows what seems to be a high explosive version of the UMLACA being launched and detonatingAs the camera tracks the flight of the UMLACA it's very distinct outline can be clearly seenIn the video it's claimed that the munitions are fired from Mezzeh airbase, and it's actually possible to confirm they are coming from the direction of Mezzeh airbase. At the start of the video we see the launch, and the outline of the hills behind it.Using Google Earth we can position the virtual camera facing north from Daraya, looking towards Mezzeh airbase, and it's clear the topography matches what we see in the videoThe structure at the top of the hill is the HQ of Maher al-Assad's 4th division, which can be seen here on Wikimapia . A report from the Institute for the Study of War examining the situation in Damascus in December 2012, shows that the area north of Daraya, including Mezzeh airbase, and the 4th division terrain to the north, were under the control of the Syrian army, and it seems, from what we can see in the above video, that the UMLACA was fired by Syrian government forces. This not only shows the Syrian army have been using the munitions, but they've been using them since December 2012.More posted on the subject of the August 21st attacks can be found here , and other posts on chemical weapons and Syria, including extremely informative interviews with chemical weapon specialists, can be found here
