The typical generic tank round is 120 mm and around 50 lbs. This is interestingly mostly the result of the intersection of ergonomics (soldier needs to be able to hurk the round around) and metallurgy/engineering of the barrel. Anyhow, that's a whole lot of pain for any vehicle that's not a peer tank, any sniper/hmg/rpg team set up in a strong point, etc, for a very reasonable price. A good tank crew can fire these at a rate of about one every 10 seconds including overlapping recognition of new targets. This is what tanks are built to do, and it's not equivalent to what drones or man portable smart missiles/munitions can do, as interesting and increasingly novel as those latter are.
