In the film "X-Men: The Last Stand", what is the name of the army that Magneto forms?

"X-Men: The Last Stand" (also marketed as "X3" or "X-Men 3") is a 2006 superhero film based on the X-Men superhero team introduced in Marvel Comics. It is the sequel to 2003's "X2", as well as the third installment in the "X-Men" film series.

Erik Lehnsherr / Magneto is the leader and founder of the Brotherhood, Magneto is a mutant Holocaust survivor who wages war against humanity in the name of mutant superiority. He has the ability to control and manipulate metal, making him one of the most powerful mutants.

In 1986, Charles Xavier (Patrick Stewart) and Erik Lehnsherr (Ian McKellen) meet young Jean Grey (Famke Janssen) at her parents' house to invite her to join their school, the X-Mansion. Ten years later, the industrialist Warren Worthington II (Ben Foster) discovers his son is a mutant as he tries to cut off his wings.

Worthington Labs announces it has developed an inoculation to suppress the X-gene that gives mutants their abilities and offer the "cure" to any mutant who wants it. The cure is created from the genome of a young mutant named Jimmy (Cameron Bright), who lives at the Worthington facility on Alcatraz Island. While some mutants are interested in the cure, including Rogue (Anna Paquin), many others are horrified by the announcement. Magneto re-establishes his Brotherhood of Mutants with those who oppose the cure, warning his followers that the cure will be forcefully used to exterminate the mutant race.
