I sometimes wonder why the rush to scifi type weapon systems for infantry.
The more geewhizery applied to a weapon system, the more potential for disruption of function for that system.
If it’s to be carried on foot, then lighter is always good, but will that overly reduce its stability while firing?
If the current MG systems carried by foot infantry aren’t powerful enough then a lighter weight heavy gun system would be appropriate. But if this is to be a vehicle mounted system, then heavier might mean more tolerance to long sustained use.
A bad day and/or an inexperienced gunner can run a MG real hot, real fast. A heavy gun system that can stand up well to abuse and remain reliable would seem to be of more importance.
But, then again, I hated it when MRE replaced C-rats. The idea that I’d have to carry even more water, just to be able to eat chow, really seemed counter competent. I guess I was wrong then. Might be wrong now too.
The new 25 mm smart round was impressive. It knows the range to target and can be fused to burst on impact, or ABOVE the target, so that you can’t hide behind walls, or in a room.
