It would be more efficient, and on practicality I could probably stand behind it. On the other hand, that's an obscene loss of life of people who are likely not responsible for their government's actions.

Unless I'm misunderstanding the scope of damage from a tactical nuclear shell. I'm thinking along the lines of the WWII bombs, but if these aren't as devastating then that's something different. If we could locally wipe out mostly-military areas that way without devastating too much of the surrounding land and people, that would be awesome
