The Astra Militarum: known with good reason as 'the Hammer of the Emperor', are possibly the single largest military force that the galaxy has ever seen. The tales of heroism and desperate futility surrounding the men and women of the Guard are many - this omnibus contains the three novels detailing the battles of some notable warriors of the Astra Militarum, as well as a number of extra short stories. Read it because It's three novels and four short stories featuring the massed ranks of the Astra Militarum (or Imperial Guard for the old school among you) up against a variety of the Imperium's enemies.
