The SDB weapon is old.
The 2nd gen of JDAM class stuff of the early 1990s.
And the rocket combo was just a mishmash of surplus components made from parts that were slated for disposition. An attempt to make HIMARS ammo cheap.
Hence my point - we were in NO CONDITION to fight a first-rate military.
Anyway, the Russians are now using fiber optic drones, so the Neocons can kiss goodbye all the expensive jamming hardware.
