What is "hammerverse"

Hammerverse (or the Slammerverse, Slammers universe, Hammer universe) is a setting for a series of military science fiction short stories and novels by author David Drake.

The series follows the career of a future mercenary tank regiment called Hammer's Slammers, after their leader, Colonel Alois Hammer.

As with his other work, Drake borrows plots from historical or mythological sources for many of the Hammer's Slammers stories. For example, he retells the story of Jason and the Argonauts in The Voyage, and part of the Odyssey in Cross the Stars. Other stories borrow from pulp era fiction (The Sharp End is based on Dashiell Hammett's Red Harvest.)

Short essays in Hammer's Slammers provide details of the political, social, economic, and technological conditions in the Hammerverse.
