This is the good stuff, two devices like this can stop entire eastern armored division. Also it's a air dropped bomb, which means it requires air superiority. It's also massive a overkill against 1 or 2 tanks, or an APC - there are few massive concentrations of armor that would warrant use of CBU-97, except for Kyiv convoy and such, but it's unlikely to repeat. The thing you need for this is either 155mm DPICM, or 155mm BONUS, which has two elements like in CBU-97 per round

I'm guessing the cluster weapons discussed are mostly tube artillery projectiles, like 155mm and maybe M30/M26 rockets, because ZSU is artillery-heavy
