Continuing after the events in Book 12: The Lost Planet, Operation Arrow highlights the unit's deployment as part of a mercenary unit designed to fill the coffers for the Dutch Protectorate. With this the unit delves deeper into the known human occupied planets and sees more than it bargains for as well as fighting the same fight or learning new things as they conduct missions from peacekeeping to direct combat as well as counter-insurgency warfare. Like most books it offers viewpoints that the author has noted as well as various references based on real world experiences and events adapted for this book.
