Suicide

As creatures that are born with an inherent gratitude to be alive, galts rarely find that life is so unbearable that they cannot continue. Galts are nothing if not accepting of the free will of their brothers however, and so when a galt chooses this path, its nonessential parts are removed and recycled while it is outfitted with major explosives--explosives that almost always are at the absolute limit of what is allowed by the Promethean WMD directive. These suicides then travel to enemy strongholds in order that their destruction may further the goals of the galts as a race. Sometimes though, suicides have second-thoughts and frantically claw and rip at their internal wiring in an effort to remove the explosive.
