   you have several thousand sensors constantly jinking with thrusters, they're   
   going to run out of fuel eventually. This means you'd either have to have a   
   resupply network    
   constantly resupplying them or you'd have to replace them. If you want to talk   
   about a huge effort, there you have it. That doesn't mean it can't be done,   
   but it does make it resource intensive.

   	No. Minor -- and enough distance to be missed by any reasonable-sized   
   hazard is minor -- deviations won't take them out of orbit, and they can   
   maneuver BACK to orbit. Sure, if you keep firing huge salvoes in a way   
   that they CAN'T, yes, you could drive them out of their original orbits   
   permanently, but jebus, you'll be spending so many orders of magnitude   
   more to shoot at them than they cost to put there that your opponent   
   will be winning on pure economics.   
      
   	Firing shotgun-concentration loads of pellets to fill gargantuan   
   volumes of space? No. Really, no, what the hell are you thinking? Let's   
   leave aside the economic and practical problems of setting up your   
   asteroid-sized shotgun loads, and note that the end result is you're   
   going to be basically making the entire near-asset (with "asset" being   
   "Earth or other area worth going to) space be filled with debris. We   
   have enough trouble with low and medium-orbit debris as it is, if   
   someone's firing gargantuan amounts of material at us, that's gonna make   
   it a pain in the ass for everyone.
