What do you get when you complete bonus objectives (with the blue plus on it)?

Sometimes you'll find a mission like "Assassinate the Assassins", where optional missions are presented.

In the mission aforementioned, it will ask you to murder certain assassins via a certain damage type, like pistols, shotguns, or melee.

Do these optional requirements add anything to the mission reward? Or are they there for nothing?

Answer 1

No, mission reward does not change.

The only thing you gain is score towards a Badass Challenge -> Badass Ranks.

Answer 2

I don't know if they add anything to the mission proper, but apart from adding a little challenge (and self-satisfaction), you also get badass ranks for completing a certain number of them.
