The aim of this book is the first of a series to provide off the shelf wargames that may be of immediate use in military training. This book contains 4 ready to use wargames: Game 1: The Sandhurst Kriegsspiel aims to allow officers to test the plan they devised in a TEWT on the actual ground using the tool of wargaming. Game 2: The Battlegroup Kriegsspiel is next level up game. While still a kriegsspiel, dependent on sound military judgement by the umpire (and players), it includes some hard operational research based tables to help arbitrate the combat outcomes. Game 3: Current Ops: the Modern Infantry Battle is a more rigid kriegsspiel, with more detailed rules to govern movement, combat, suppression and ammunition expenditure. Game 4: Counter IED Kriegsspiel is an excellent example of using some of the recent developments in wargaming to create an engaging game about when faced by an IED threat. This book is part of a series documenting current practice in professional wargaming.
