The ritual phrase with which Jem'Hadar soldiers pledge themselves to the Founders before combat, declaring that they are already dead and can reclaim their lives only by winning.
Victory is life is the central saying of the Jem'Hadar, the engineered soldiers of the Dominion. It closes a short rite spoken before battle. The unit's leader, the First, declares that he and his men are dead from that moment and go into battle to reclaim their lives, because they are Jem'Hadar. The soldiers answer with the phrase.
The rite is first heard in full in the Deep Space Nine episode To the Death, when First Omet'iklan leads a joint mission with the Defiant's crew against renegade Jem'Hadar. O'Brien offers a human reply, that he is very much alive and means to stay that way.
The saying recurs through the Dominion War. In Rocks and Shoals Third Remata'Klan pairs it with a second maxim, that obedience brings victory, as he leads his men into an ambush he knows will kill them.
