Flag Kill

The Flag Kill Medal medal is awarded and achieved for killing an opponent by assassinating or beating down your enemy with the flag in your possession. You get this medal in addition to the Beat Down medal (or an Assassination Medal depending on where you hit you opponent). It is represented by a white eight-pointed star with a red flag in the middle.

The medal can also be earned by shooting a weapon (such as a Rocket Launcher), grabbing the flag before it hits the target, and killing the target with the rocket.

Trivia

 * On your Halo 3 Career Stats at Bungie.net, the description for the flag is 'Its right next to the headlight fluid'. This is homage to the series Red Vs. Blue, where the red team sends the rookie Donut to the store for elbow grease and headlight fluid. Instead, he mistakenly goes to blue base and takes their flag.
