Cyborg infantry are the result of recent Nod experiments in melding Tiberium-mutated humans with machines. They are armed with heavy body armour and a high-power pulse rifle that is particularly effective against infantry and light vehicles. They are resilient to anti-infantry weapons, but are more vulnerable to anti-armour ones. If a Cyborg is badly damaged, his legs are detached so that the rest of the body can fight on. Cyborgs heal in Tiberium. Perhaps a bad impersonation of Arnold could work.
