It’s called the CARDOM, and it’s based on the M113 APC.

It includes digital systems to lay the mortar on target in less than 30 seconds from receipt of coordinates, and then can fire with a burst rate of 16 rpm, followed by a sustained rate of 4rpm.

I will simply note that it does everything that the Future Combat Systems NLOS-M (Non-Line-of-Sight Mortar) does in a lighter, and much cheaper package.

This stuff isn’t rocket science, so why is the US military paying rocket science prices?
