Hey, thanks for writing this.

unitary airburst shells offer similar capability, but these are rather uncommon for some reason

Really? I thought that was the standard type of shell. Do the typical unitary shells detonate on impact with the ground, then?

Ukrainian drone operators are also using single submunitions, presumably from cluster bombs, as drone dropped ammunition (i’ve seen at least three separate videos of this). these things are well suited for this role and are used in vastly smaller numbers minimizing UXO issues in the future

Oh yeah, I hadn’t considered that. And seeing as some of these were at end of life anyway it actually makes sense as an alternative to an ordinary infantry grenade.
