I operated a M113 as a mortarman, the 120mm barrel mounted to a swivel base in the floor with the barrel facing towards the rear. It would rest in a mount attached to the base above the rear hatch door. You first had to open the top doors to make room to deploy the mortar and could only swing it about 45-degrees from side to side, so if you needed to adjust for a different target the tracks would need to be moved, aiming posts realigned to the new angle, firing to bury in and then you're ready for a fire mission.
I'm curious to know more about this new variant. How roomy it is inside the passenger area, how mechanical is the turret operation, can it fire in all directions, if not why was the decision to face the barrel towards the front...
This AI video is saying it's automated, breach-loaded and there will be a demonstration in September. We also used to run 3-5 man crews where this seems to serve 3.
We need a successful replacement to DirectX for this to happen.
Look how desperate they are now for their web browser, imagine when people start abandoning Windows because there are other options that work just as well. I can't wait.
