Sting like a Talon - Call of Duty: Black Ops III

In Campaign, Kill 20 Enemies while flying the same Talon - 20

This can be done in any level but it is the easiest to be in Mission 2: New World.

You need to continue through the mission to the part when you are able to hack into a combat robot and control it. You have the choice of a Talon or a Hound. Choose the Talon and continue to kill 20 enemies with the Talon Drone.

This a reference to the quote from the famous boxer, Muhammad Ali - "Float like a butterfly, sting like a bee."
