Hero

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". Battle, military command and operations...and a young man who must overcome his terror while dealing with his fellow soldiers and fighting an enemy force in a guerilla war on the planet Neuva Terra, that tests the mettle and the reputation of the galaxy's finest soldiers-for-hire.
