I think you have a misunderstanding of how the technology works. A LRF will only tell the snake eater how far away from the target he is, and if it's tied to his GPS a 10 digit grid that is NOT accurate enough for a JDAM. We routinely train our studs that the grid they get from the Vector/DAGR combo is only good out to about 8 digits. The snake eater likely will have PSS-SOF which will give him a JDAM quality grid. After all, a JDAM is a GPS guided weapon. You need a hyper-accurate grid in order to drop BOC (Bomb on Coordinate). If you drop BOT (Bomb on Target), the aircraft systems are the ones that generate/refine the grid.
A more accurate statement would have been "...what a snake-eater with a laser target designator and a BONE with a belly full of GBU-12s can do."
What's "JDAM quality?"
I'm curious how accurate "hyper-accurate" is, since IIRC 10 digit grids give 1m resolution...and an extra 1m on top of weapon CEP doesn't seem like it would change things too much.
