The Armadillo Trooper is a special version of the Assault Trooper. They serve as security at Stahl Arms on Helghan during the Vektan Cold War, rather than Security and Riot Troopers. They use powerful personal shields that greatly helps protect them. The OWL's stun mode and charged up shots from the LSR44 Spoor are used to disable them. They can be killed instantly by running up to them, and using Brutal Melee, but it must be done quick.
