Optimized Caliber

[Tony Williams]

Guided mortar rounds have been developed in 81mm and 120mm. Doing the same for 60mm would be more difficult, but may be technically possible. The challenge would be convincing the bean counters that it'd be worth the cost.

Actually, not a problem. The current ATK and GD-OTS guided mortar rounds use standard bombs with a fuze/guidance unit screwed in the standard fuze aperture. This will fit in 60mm mortar bombs as well. The only issue will be whether the cost of the fuze is worth it for the small bang - it might be, for arming small UAVs for instance (which is where the current interest in guided 81mm bombs comes from).
