As they jerry-rigged it with a grenade fuse, I’m pretty sure it’ll work against infantry just fine. Drop it from above with a delayed fuse and it’ll clear a sizable area from anyone unlukcy enough to have their head above the ground.

With that kind of payload I suspect that it can’t get too far away before batteries are empty, but I suppose it’s built for a reason. Getting that much explosives reasonably accurately over the field you’re pushing could be pretty useful.
