Furthermore, sometimes the Tyrant would use the huge claw on its right arm to bat the grenade away. Although the intense collision would cause the grenade to explode prematurely, it still took time to react. Therefore, during this explosion delay, the grenade had already flown some distance, so even if it exploded, it wouldn't cause much damage to the Prototype Tyrant.
Zhang Yanhang could understand why the Prototype Tyrant was capable of catching grenades or batting them away, despite its extremely low intelligence level. After all, it was a biological weapon developed by the Umbrella company, so the Umbrella company would definitely equip them with knowledge on how to counter modern thermal weapons.
Moreover, not only did they learn to counter modern thermal weapons, but in the later stages, they would even train Tyrants to use modern thermal weapons against their enemies.
