Halo ODST: Project Valkyrie

Orbital Drop Shock Troopers; It is said one ODST can take on an entire squad of Marines with one hand tied behind their back, I don't know about the average Trooper but their once existed a single team of ODST capable of taking down an entire battalion of covenant forces with little to no aid. What could extinguish such a flame you may ask? Humanity's Darkness. This is their tale.
