Yep, they look like Chicom 107's. We got hit with those fairly often too, well until the 155's really got rolling on counter battery anyways. Had one on Nov 11 that came in just over the Hesco inner wall, hit the concrete vehicle pad broke up without detonating and hit a Sgt from Comm plt in the leg/ass. Just heard the other week he was walking again. Have not seen a whole lot of 122's around N Babil, probably because they can't just lay it on the berm and light it off as easily as the 107's. The unit previous captured a 122mm improv launch assembly using tubes cut off a BM-21 or similar launcher, a lot of fabrication work went into that, and they're too big to move fast enough to easily get away from counter battery fire. But they were not shy about using the warhead sections for IED's instead
