East Coast Brotherhood of Steel characters

In Fallout 3, the Brotherhood of Steel is comprised of ~120 members (95 combatants and 28 non-combatants). These are the confirmed numbers in-game; the real storyline number of the East Coast Brotherhood of Steel would be far higher. With Broken Steel more Brotherhood of Steel soldiers can be found in areas that the Brotherhood has captured from the Enclave making the numbers higher than they were before the events of Broken Steel.
