Let's not kid ourselves.

Modern airborn warfare techniques made civilians military targets before most of us were born.

Civilians create the wealth and the military material which support the military.

Hence, mankind now often targets the source of the wealth that supports their enemies....civilians.

As to the specific horrors we rain down upon armies and the civilians who love them, alike?

Well, none of them aren't crimes against humanity.

Antipersonnel cluster bombs are part of that deadly arsenal of man's inhumanity to man.
