Tactica Imperialis: A History of the Later Imperial Crusades

This is a Warhammer 40,000 background book, emulating in tone the Sabbat Worlds Crusade, though describing a number of significant battles/campaigns in Imperial history. The book comes from the perspective of an actual educational document of the 41st Millennium and as such is packed with diagrams, maps, artwork, photos and numerous facts and figures of these battles.
