For the clan!
The Martyr is a suicide bomber used by the Forsaken.
Martyrs are sickly mutants near the final phases of their Tiberium transformation. In order to save their fellow mutants from the burden they would become, they have chosen to give up their lives in suicide missions. Their sacrifice is highly venerated among the Forsaken.
Martyrs are often packed with explosives and used to carry out suicide attacks, detonating themselves upon reaching the target. Due to the irregular supply of Martyrs, only a limited amount can be trained at a time.
