Hmm.

I think that a cruise missile that dispenses multiple random-delay delayed-fuse munitions that could be dropped on Russian supply lines could be significant.

Munitions like that are used to make it hard to repair something after it has been destroyed.

Dropping a number of such things onto the Kerch Strait Bridge or similar supply chokepoints might not destroy them, but it could make them too dangerous to use.

Despite all the talk of game changing wonder weapons, the weapon system that is responsible for inflicting the most casualties on both sides in this conflict is the same as WW1 more than a century ago, tube artillery.
