Personnel

Personnel zombies are slightly stronger than normal zombies, but are technically not special zombies, as they have no special characteristics besides. Depending upon their uniform or appearance indicates different levels of damage-dealing strength, speed, or health. The best way to deal with these zombies is effective use of the rifle's piercing charged shot (hold R1). If you feel overwhelmed, use a flare or molotov. Do not underestimate these zombies, or you will become surrounded very quickly.
