Other than that, I am struggling to think of scenarios where the better accuracy will justify the significantly higher unit cost of these shells.
What I think would be more useful would be precious guided mortar rounds for light infantry and airborne.
These troops will have limited carrying capacity, so it's extra important to make every shot count.
The nature of these troops types will also mean they are far more likely to be in close contact with the enemy, so weblike have a much better chance of regularly having forward elements in position ready to guide the rounds in.
