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.
I remember seeing that showcased on one of those future weapon type programs on TV.
It is impressive, but I also remember my first thought was “just more stuff to go wrong”.
The opportunity for the “*&*& me!” demon to step in and play goes up exponentially for each moving part and is multiplied by each electronic component.
