Find Replacements — stalker

Degtyarev : I have connections in the Zone. I could find you some new guards.
Herman: That would be wonderful! They will be given full scientific support and the latest technological developments in exchange for their work! You'll get a reward, too!

Hermann and Major Degtyarev discussing the new guards

Guarding the scientists is a mission available in S.T.A.L.K.E.R.: Call of Pripyat.

Description

The mission can be taken only after Black's team of mercenaries has been eliminated, either as a result of the mission Last developments or if the player attacked the bunker and killed the guards (which will also turn the researchers hostile, and potentially unlock the mission Research group). The player must find a new group of guards for the bunker now that the previous ones have been either killed or abandoned their mission.

There are four candidates for the protection.

Spartacus: In order to be able to hire Spartacus, one must have sided with the Loners in The Hit and Transaction, and managed to have Spartacus survive both raids. Afterwards, he can be found aboard the Skadovsk. If the player asks him, he will move to the lab with a group of stalkers.
Hatchet: In order to be able to hire Hatchet, one must have completed the Food mission for Hatchet. Once done, the player can approach Hatchet and offer him to work for the scientists, after what he will move to the lab with five of his men. The player needs to be careful as hanging too close to the mercenaries' camp with a weapon out will cause Hatchet's group to become hostile.
Duty: The player can simply ask Shulga to send a group of Duty fighters to the lab. This is the simplest option (along with the Freedom one) as there are no prerequisites and Shulga is found in Yanov station, not far from the scientists' lab.
Freedom: The player can simply ask Loki to send a group of Freedom fighters to the lab. This - and the Duty one - are the simplest options as there are no prerequisites and Loki is found in Yanov, not far from the scientists' lab.

Note that it is not possible to hire Duty if Freedom was hired for the Research group mission, and vice versa.

Once the player has recruited someone, they can speak to Hermann to get the reward.

Reward

The reward for this mission is 4000 RU, two psy-blocks, three antidotes and three radioprotectants.

The mission does not contribute towards getting any achievement - recruiting Duty or Freedom to guard the bunker will not help the player get the A Friend of Freedom and the A Friend of Duty achievements.
