Okay, the F-15A/B/C/D will never have the capability. The USAF made the Strike Eagle for that purpose, and no F-15Cs have been known to have previously in any theatre seen carrying any matter of air-to-ground ordnance. As a JFO, it's my job to call in CAS, so I know for a fact I'll never get a Charlie model F-15 in my request whether it's in Iraq or Afghanistan. Also dropping a Paveway is more complicated (well it's not too difficult really) than you think, so first off, the F-15A/B/C/D models at the minimum need the required electronics to "see" the laser spot first, a la the A-10, so no it cannot even use those, as it's main function (and only) is to kill planes, and not provide any sort of ground attack capability.
