Alpha Contracts

Long before CASPers ruled the battlefield, a hundred mercenary companies took Earth's first alien contracts, and only four came home. Alpha Contracts tells how Jim Cartwright, Kuru Shirazi, Lawrence Kosmalski, and Altan Enkh became the founders of the Four Horsemen, following their companies, and a fifth, the ill-fated Avenging Angels, through the missions that made and nearly broke them. The origin story behind the whole series.
