a mk-82("dumb bomb" and relatively cheap), with a "smart bomb" guidance kit attached becomes a gbu-12(laser guided, much more expensive), or a gps guided gbu-38(very expensive jdam). it's most unlikely a precision bomb would be used on a relatively isolated, stand alone target. a "dumb bomb" means it's not guided to a precise point after leaving the aircraft, but a fighter jet's weapons delivery system can still put it right on the target. it's not like its a hit and miss proposition. why spend $20-40,000 when $300-500 will do the job nicely.
