Games Workshop Warhammer 40000: Codex Astra Militarum

The Astra Militarum is the first, and often last, line of defence for Humanity. It's the largest coordinated fighting force in the galaxy, with ranks of trained and equipped soldiers tithed from countless planets and united by their faith in the God-Emperor. With grit and determination, Astra Militarum soldiers obliterate their enemies with a combination of concentrated lasgun fire, massed artillery, and mighty battle tanks.
