I request, a new type of missile launcher that I do not believe has been done before. It should fire a large missile, that is manually guided to the target like the Coalition one. But at a set distance to actor, terrain, or whatever, splits into four accelerating unguided HE-Frag micro rockets in a shotgun like pattern. And the casing from the delivery missile continues to fly towards the target just behind the submunitions, inertly kinda like a modern cluster bomb, that would deliver a mass only punch. And perhaps the rocket motor would continue to burn in an attempt to penetrate or carry away the target. I would attempt this myself but this is way above my skill level

We have this already. It's not exactly like you described but it's pretty close.
