Necessity is the mother of invention. A homemade howitzer. Interesting bit by Tyler Rogoway: http://foxtrotalpha.jalopnik.com/meet-the-hell-cannon-the-free-syrian-armys-homemade-ho-1628114916
Did you see the guy on welding duty? Or the use of a pick axe to help load round... A miracle it shoots...But, in a pinch...Maybe they were trying to infer it had some gas attack capability? Why use propane as an explosive when other stuff is prolly more effective.
No miracle there. It's just a huge honkin' piece of pipe with wheels. The "miracle" is that the can construct the spigot mortar rounds. Still, I fear that they are fugitives from the law of averages, and that the law will catch up to them in a rather spectacular way. No, it does not sound as if they are using propane as an explosive. the article says that they are using old propane tanks(as a casing) with which to make the shells, and then filling them with a "crude explosive mixture." Probably homemade powder or some such.
