Cavalier

Cavalier is a Halo 3 Meta-game achievement. It is earned when the player earns 15,000 points while playing the Meta-game on. This achievement is worth ten Gamerpoints to the player.

A blue circle with a winged sword, also known as the Valkyrie emblem, represents this achievement.

Methods
Note: See Guerilla for standard techniques.

Turn on the Thunderstorm, Famine and Fog Skull. These are probably the three easiest Skulls. Warning:  whatever you do, do not turn on the Catch Skull because on Tsavo Highway, there are many Grunts along the road and they will be randomly throwing Grenades at your vehicle. With Thunderstorm on, the effect will be worse as the newly-promoted Grunt Ultras will pull a lemming and kamikaze run at you. It is important that you have a Brute Chopper with you as well, as it is probably the sturdiest solo vehicle. The other choice would be the Warthog, but after a while the Marines die and you won't have a person to man the Turret. Also, turning on Tough Luck would cause even Grunts to dodge your vehicle when you attempt a splatter. This should most likely be played on Heroic or Normal, depending on your skill.

Another way is to get in the Transport Warthog. Arm Marines with heavy weapons, such as the Fuel Rod Gun. Every chance you get a Fuel Rod Gun, give it to a Marine, they'll have unlimited ammo, and it's possible to get all of the Marines armed with Fuel Rods. The rest will run smoothly.

Trivia

 * Cavaliers were Royalist horse riders during the English Civil War. More recently, the term means a "devil-may-care" attitude. The award is called "Cavalier" because most of it is vehicular combat.
