David Drake is a successful author of science fiction and fantasy literature.
He is one of the premier authors of the military science fiction subgenre. In addition to his own works, he also often contributes the military angle to many collaborative works. His co-authors include Karl Edward Wagner, Janet Morris , S.M. Stirling, and Eric Flint.
His best-known non-collaborative work is the Hammer's Slammers series of military science fiction. He also contributed outlines to the Belisarius series series (written by Eric Flint), and the General series (written by S.M. Stirling). Drake is listed as a co-author of these (and many other) books, but he openly admits that he did the smaller part of the work.
