Alan Anderson is an UNSC Army Trooper and Special Operations Army Shock Trooper. He was born in 2500 to Gary Anderson and Melisa Kaitlyn Ray. Alan's parents died in an insurrectionist attack when he was nine. The attack also killed his three sisters, prompting him to seek revenge. The then Corporal Anderson was never punished severely, mostly because of his extreme loyalty to the UNSC and his superiors, and this was the first time he had ever acted against orders or showed any kind of hostility towards his allies in his then ten year career.
