Spartan Officer

Spartan Officer is a Halo 3 Multiplayer Achievement. It is earned when the player gains 50 experience points in a certain playlist and a rank of at least Lieutenant on Xbox Live. This Achievement gives 25 Gamerpoints to the player.

It is said by a few players that they got the achievement at the same time as the Vidmaster Challenge: Lightswitch Achievement, and it didn't go through. If this happens, read the note below. Others did not get the achievement when advancing to a Highest Skill of 10, skipping Lieutenant, Grade 1.

It is represented by a gold plate with an eagle holding three black arrows and a black thunderbolt, with three pips behind it.

It unlocks the Rogue Helmet for multiplayer use.

Note: If you have achieved the Spartan Officer Badge and haven't got the achievement, you can still obtain the achievement by getting a lieutenant rank in any of the new playlist-specific ranking systems.
