They do not need requisition (the main resource of the game, Necrons will get a a boost to their build times instead when capturing strategic locations), the Necron Warriors are free (although they take a long time to build, and the more Warrior squads you have, the longer it takes to build them), as well as the resurrection ability (which means that destroyed units have a chance to come back to life, which can take the Necrons above the headcount limit).
