These compact volumes are bursting with information, but the visuals are their real strength. Filled with full-bleed, full-color action photos and concise texts, the pages are also peppered with “Xtreme Fact” sidebars that add related information. Well suited for reports or pleasure reading, the books are so current that Navy Seals includes information about Seal Team 6’s attack on Osama bin Laden’s compound in May 2011. History chapters, though brief, are enriched with engaging reproductions. The texts are brief but not easy, making the books best suited to older reluctant readers.
