I lack the time to do this very useful document justice. Much of this information does exist in public US intel documents, but it’s a hassle to consolidate it all and there are issues with consistency.
I would point people to the delivery vehicles section…no other public official document has such a list of vehicles, ranges, and CW agents, as far as I know. Ditto for the composition of the Syrian CW agent stockpile. Also notable is that Syria is developing another mustard agent and a nastier form of nerve agent.
Lastly, the report’s observation that the regime “is adapting its tactics and the munitions in its stockpiles to a terror use against civilian population” is perhaps the element with the most far-reaching implications. One wonders if other regimes are getting ideas; governments, including the government of Syria, produced CW arsenals in the past for quite different reasons. There’s a decent amount of detail on that point, so take a look.
