  Oh it's certainly cheaper than blanketing an area in artillery, but I doubt it's cheaper than the grenades and bombs their dropping from similar drones, which can return and rearm.
  I'm assuming their using different drone models for these missions
context: Think of it as low cost alternative to GPS artillery.  It is slow and it can be shot down but it is cheap and accurate. >
  
  Not particularly effective though. Even if you crash it in a trench your only getting 1 or 2 casualties.  The effect on moral will be rough, but so is just having a hand grenade fall out of the sky and land in your foxhole >
  
  its a price per kill style calculation, and it still adds up well.
  some of these drones are worth less than what russia promised(but ofc doesnt) pay the family of killed troops. even so, a 100k HIMARS missile for 20 vatniks vs a 5k or less drone for an individual... hell, iv heard of suicide drones potentially being 1k or less if the explosives are avaliable... basically a body for a mortar shell
  so use both, have the loitering drone watch the 'single use drone' impacts, and drop its grenades where needed after + command now knows exactly what damage was done.
