Captain of the Guard

Captain of the Guard is a title granted by the First Citizen of the Vault City to exemplary citizens that have gone above and beyond the call of duty to protect the city's interest and independence. In essence, it is the highest military rank one can hold, giving him full authority over the military might of the Vault City.

In Fallout 2, the Chosen One can attain this rank if he compliments Lynette enough and completes the exchange between Westin and her.

Obtaining this rank within Vault City will allow the player to go back to Citizen Sergeant Stark in the Corrections Center and demand that he pay Cassidy compensation for damaging his bar, which will earn the player $500 and 500 XP. It will also allow the player to bring Marcus and Lenny into the inner city without being stopped by the guards. Bringing Marcus to the Vault doctor will earn the player XP and a considerable amount of ammo, as he pulls years of accumulated bullets out of Marcus' body.
