|“|| ... the Colonel flipped his lid and shot two people at point blank range and then himself... Now I'm on my own in this damn anomaly...|
- General Tachenko's remarks about Colonel Kosmach
Call of Pripyat
Colonel Kosmach was one of the founding members of Duty who conspired the communications break-down to desert the military and was eventually stuck in a Space anomaly during an artifact hunt. Colonel Kosmach's corpse can only be seen after the player uses a Svarog detector near the cooling tower which causes the Space anomaly on top of it to implode, dumping the people inside it. According to General Tachenko's recording: Kosmach went insane in the space anomaly and killed 2 people before killing himself.
- He most likely killed Lieutenant Zakharchuk and Lieutenant Bunchuk during his insanity breakdown, seeing as only him, the general and the two were left.
