Check. I'm going to be an MLRS guy here in a few months.

DPICM isn't used in either theater right now, which marginalizes the system from the start. The M31 provides a 51.5 pound HE warhead and is a PGM, so it has more use in current operations. The dud rate on older DPICM systems was 4% and they are now going to >1% dud rates in order to prevent UXB on the battlefield.

Danger close on MLRS is 2,000 meters. That is more than three times are far as tube artillery. With M30 or M31 you can get a lot closer. M30 uses a guidance system and DPICM.

There are a number of missiles as well, but with a 70-300km range (depending on which missile we are discussing) they are in a completely different class and employed much differently.

Which brings me to my initial thought when I opened this thread several years ago. There are a number of different fire support systems that have different advantages, disadvantages and methods of employment.
