Imperial Infantryman's Uplifting Primer
A tome of off-world secrets
The Imperial Infantryman’s Uplifting Primer is a text that appears to be a compilation of information useful to soldiers in the Imperial Guard or Departmento Munitorum. A copy of the book was found for each soldier killed at the clearing where the Departmento Munitorum Loot was recovered.
The books themselves are remarkably similar in physical form and handwriting, clearly the work of a single scribe. Each book is small enough to fit inside a pocket (indeed, several of them were recovered from the pockets of the dead men), with very thin pages. They are bound in some form of leather, and include several woodcuts.
