I love the design of this. Good low RCS design for an affordable price. Very useful for asymmetric warfare with a low footprint.
For a high subsonic drone, I thought it is retarding parachute fall to increase the aerodynamic drag. Check this out for Karrar:
The barrage of missiles remind me of a wargame back in 2006 where they demonstrated that ability to launch enmasse because the trolls were questioning the number of trucks Iran could field back then. I remember the visual impact was quite immense back then and shut some mouths for a while.
