This book describes well the extraordinary range of troop types and their uniforms, included examples of the complex range of unit cross-postings between formations. There is a helpful, albeit brief, historical overview, then chapters on the Nationalist army (including militias), colonial troops, and foreign volunteers, plus the air force, navy and security forces. The text provides useful information on the state of training and 'combat effectiveness' of the various troops, and plentiful photographs and illustration to assist the modeller/gamer. Company and battalion structures are provided, although the author makes plain that these were often theoretical rather than kept to in the field. The back cover implies that there will be an accompanying volume on the Republican forces: together these will provide a nicely balanced profile of troops, uniforms, styles of fighting, weapons, and so on.
