A fully trained pilot.
A veteran pilot of the Brotherhood.
The highest lancer rank. A captain usually helms the largest of the Brotherhood's vessels (the only existing one is the aforementioned Prydwen) and is responsible for overseeing their day to day operations, answering directly to the elder, though lancer-captains may also pilot Vertibirds on delicate missions that require a great deal of experience and finesse.
↑Shadow of Steel quest description: "The Prydwen's captain, Lancer Captain Kells, has ordered me to attend an address being given by Elder Maxson, the supreme commander of the Brotherhood of Steel." Note: That Kells is referred to specifically as "the Prydwen's captain." Furthermore, lancer-captains may be encountered in random encounters at higher levels.
