William H Keith, JR's book, "Bolo Brigade" (ISBN 0-671-87781-X), is his second contribution to Keith Laumer's Bolo story line. On the edge of the galactic arm and human occupied space, known as the Concordiat, lays the Strathan Cluster Confederation. The Confederation consists of thirty-six human inhabited worlds that gained their freedom from the direct control of the Concordiat, but still maintain an alliance with that larger human political body. Part of the alliance between the two governments is the deployment of sixteen very old, but still powerful ground based war machines, fourteen Mark XVIII and two Mark XXIV Bolos. The Mark XVIII Bolo , was almost the last design to be equipped with only the most advanced super computers of their day, while the two Mark XXIX Bolos, named Freddy and Ferdy, were fourth generation designs using a self-direct and self-aware computer. Lieutenant Donal Ragnor, a Bolo Tactical Officer of the Concordiat, has been transferred to the Confederation as liaison officer as punishment for bucking the Concordiat military chain of command. Soon after Donal's arrival on Muir, the capital world of the Confederation, he discovers the Mark XVIII Bolos have been deployed to fourteen different worlds and that he will be the commanding officer for both Mark XXIV Bolos stationed at the capital. Further, prior to Donal's arrival two member worlds have fallen silent and several starships have disappeared from the space lanes within the Cluster. The Cluster's central government assumes that the loss of communications is due to equipment malfunctions and that the some of the lost ships have been captured by pirates, while others are being reported means of committing insurance fraud. However, the government does not send out investigation teams to verify their theories. After Donal's arrival, Muir receives a garbled message from the world of Wide Sky, near to the edge of the cluster, about an invasion, before communications abruptly cease. Lieutenant Ragnor, Freddy, Ferdy, and Alexie Turner, Wide Sky's Deputy Director General, have to fight off the invasion of an unknown intelligent species on Muir. William H. Keith, JR brings the reader another well-balanced story in Keith Laumer's Bolo saga. This book is another gem for the reader who likes the writings of William H. Keith, JR and Keith Laumer.
