What first came to mind as to what said weapon was that it was the Armbrust
. It had recently procured in smaller quantities before and it is being made by an ally, Singapore.
Then again, the Armbrust is a recoilless rifle. The propellant is in the launcher not the projectile. Both the Meejuh and GPh-released Lit mention newly-procured weapons to be a rocket-propelled grenade
Furthermore, Singapore is replacing them with the MATADOR
(below). I've seen 2 vids of the weapon being demonstrated:http://www.youtube.com/watch?v=i2MNSTJOwAI&feature=relatedhttp://www.youtube.com/watch?v=ZHx9rneYL88
The 1st vid by Discovery channel said it's a rocket. In the 2nd vid (produced for/by the Singaporean Military), it was described as a development of the Armbrust. The Singaporean-Israeli MATADOR borrows the folding grip, trigger and sight of its predecessor. According to the Singaporean Vid, it helps Armbrusters transition easily and it also has a mechanical firing mechanism.
Could this be the RPG we bought?
