Failsafe Detonator
From Warhammer 40k - Lexicanum
The Failsafe Detonator is a battlesuit-mounted special issue device, more commonly known as a self-destruct device. If a unit is in danger of being overrun and the situation is sufficiently desperate, a character can active this device, causing his battlesuit to explode in a deadly blast, almost guaranteed to destroy everything around him. This will, of course, lead to the demise of the pilot but could save the rest of the squad. It is seen as the ultimate expression of the Greater Good.[1]
