In the TV show "Babylon 5", what was the name of the elite force whose purpose was to fight the Shadows.

The Anla'Shok are an elite fighting force, originally founded by Valen during the First Shadow War to stand apart from the feuding Warrior Clans of the age. In Valen's words, they were to be "a military group dedicated to nothing less than preserving the future and all life. Even our enemy's life, if possible." The word "Anla'Shok" is loosely translated into English as Rangers.

The Anla'Shok were founded on Minbar by Valen during the First Shadow War, shortly before the formation of the Grey Council.

When Jeffrey Sinclair revitalized the Anla'Shok in 2259, there was still discomfort among some Minbari about them. They therefore built training centres near other races, such as on Zagros VII.

With the formation of the Interstellar Alliance at the end of 2261, the Anla'Shok were incorporated into the Alliance structure as the means to create the peace, patrolling the borders of member worlds and making sure that if one race planned to attack the other, all would know about it.

In 2266, following the Drakh attack on Earth and their release of a bio-genetic plague, ISA President Sheridan tasked the Anla'Shok with searching the galaxy for a cure and coordinating with the new starship Excalibur to follow up on anything they might find.

By 1002262, with Sol unnaturally approaching nova, the Anla'Shok were the last to download the last of Earth's records and evacuate to New Earth.
