The mini-boss of Sector 3. Appearance: He wears a dual-lens night vision device and bandages that cover his entire face and head.

He wears a neck protector. For his lower body, he wears layered leg guards over Lasonian infantry uniform pants and combat boots.

Just a bit more and I'll shoot you in the head!!!) If hit by a flashbang, he fires his gun blindly in all directions. Height: 178.7cm Age: 34 Personality: Cold-headed and frigid.

The boss of Sector 3. He first appears via radio, taunting the player. Example 1: (In Russian-accented English) Oh, finally the scramble is running. I can hear your footsteps from afar, you pigs. Example 2: (When executing the player) (In Russian) Die! Die! Real Name: RIN (Real names may vary by individual.)

Sinitsyn Komarek is a commander (Lieutenant) of the Republic of Lasonia Infantry Garrison [RIF], aged over 50. He is a very intimidating and heavily armed soldier.

Enemies from the RIF faction appearing from Sector 3 onwards. Armed with rifles. They attack the player from a distance with rifles from fixed positions. Their accuracy is quite high, but as a penalty, they do not fire immediately upon detecting the player; they start shooting after about 1 second. This timer does not reset even if the player hides. Once the reaction time has passed, they can fire as soon as the player is visible. They occasionally stagger when taking a certain amount of damage, but they do not stop firing. They also deal 10x damage to the infected. This includes all non-infected enemies mentioned later. When stunned by a flash effect, they fire their guns randomly in all directions. Since they are not infected, they are also hostile toward the infected. Appearance: Lasonian infantry uniform and pants, tactical helmet, and dual-lens night vision goggles like Yakov. The waist of the ballistic vest has many square pouches. They wear gas masks. Weapon: AK-74 with a scope. Upon seeing the player or infected, they scream in Russian like Yakov and begin firing.

Despite the name 'Medic,' they have almost no differences from the infantry above, lacking any ally healing or buff gimmicks. The only differences are that they move instead of firing from a fixed position and wear a white ballistic helmet. Think of them as mobile infantry. As mentioned before, they have the same accuracy as the infantry, so do not let your guard down. When stunned by a flash effect, they fire their guns randomly in all directions. Since they are not infected, they are hostile toward the infected. In the latter half of Sector 3, a RIF Medic can be seen treating a wounded soldier. This specific medic does nothing but provide treatment and does not react even if the player approaches. Appearance: A white ballistic helmet with a green healing cross, dual-lens night vision goggles, Lasonian infantry uniform and pants, ballistic vest, and many square pouches on the waist. They wear gas masks. Weapon: AK-47. Upon seeing the player or infected, they scream in Russian like Yakov and open fire.

Appearance: Black Menlo MGF uniform and pants, shoulder protectors, ballistic vest, tactical helmet with visor, and a gas mask where the eyes are visible. Weapon: A shotgun with the stock and pump painted mint green, a tactical riot shield with a built-in flashbang, and a taser. He accidentally entered Sector 3, which is full of RIF units from Lasonia—a nation hostile to his own Republic of Menlo. Personality: Prickly.
