Fail-safe detonation system

From Halopedia, the Halo wiki

The MJOLNIR Powered Assault Armor is equipped with a fail-safe detonation system. If a Spartan is killed or wounded fatally, or they are forced to shed the armor in the field, the self-destruct protocol will have to be enacted by either themselves or a nearby Spartan. This is done to avoid capture of the suit and/or the wearer for identification or technological study.[1]


The tiny access panel at the back of the suit is opened to activate the protocol, it is activated by typing several digits only Spartans know. Once activated, a fifteen-second countdown timer starts. Once it hits zero, the suit's fusion reactor overloads and burns everything in its path in a ten-meter radius with a follow-up explosion to finish anything alive.[1]
