If anyone wants, here's an extremely optimistic 2009 Brookings Institute white paper on how various hostile actions against Iran would play out based off numbers and history.

Chapter 3 analyses a "boots on the ground" invasion (the occupation would require a draft), Chapters 4-6 analyze American and Israeli airstrikes. Neither of them expect Iran to employ masses of drones or close the strait, and they consider ballistic missiles against US assets unlikely.

While they have an extreme western bias, there's no way you can twist the numbers to look good.
