      i thought that RG-42 was smooth inside, and i still think that RGD-5 is

      anyway, these are still not pre-formed fragments, because some of these grooves will not cause fragments to separate

      it’s not that different from any other weapon that throws around fragments, just that PFF covers highest area or whatever metric you choose per kilogram of weapon. this works only if you don’t care too hard about cost and can ignore some engineering constraints (such as acceleration survivable by weapon etc)

      e: you can see in that video at 5:50 how a few of these squared remained unseparated as a single fragment

        My point is that new weapons are better than old ones but they’re still fulfilling the same intention. It’s not like the inventor of the old grenades wouldn’t jump at the chance to increase the lethality of their creations.

        The GMLRS used in Ukraine are also optimized for fragmentation and nobody is complaining because they’re fired at military targets.
