IMHO

Metzada is an inhospitable planet of Epsilon Indi whose inhabitants -- most descendants from refugees forced to leave Israel -- can survive only because its men are highly skilled mercenaries, Metzada’s one export that brings in revenue. When young Ari Hanavi freezes in combat twice, he has one last chance to survive and even become a “hero”. Scenes of battle, military command and operations are expertly portrayed in this novel about a young man who must overcome his terror while dealing with his fellow soldiers and fighting an enemy force. Set in the same world as Not for Glroy, which David Drake called “a swift-paced, brutal, excellent political novel about the soldier of the future”.

On a planet that was once part of a vast interstellar civilization, humans survive on the edge of barbarism amid the ruins of the once-great empire.
