After obtaining the information about the Solder, you will Knowing he's holed up in a nearby "realm" - a large military base - infiltrating this place will be tricky.
How to find the Solder NPC in S.T.A.L.K.E.R. 2 Heart of Chernobyl
After getting intel on the Solder, you'll learn that he's hiding out in a nearby "field" - a large military base that will be tricky to infiltrate. Fortunately, there are several ways to gain access to the base's gates, bringing you closer and closer to the solder.
Follow the orange icons on the compass until you reach the outer wall of the Realm, which surrounds the entire massive structure. When you get here, start going around to the far right side to avoid being spotted by enemies. You'll eventually find a long metal bridge that leads directly to the base.
Although the bridge has been destroyed in some places, you can still use it to enter the base. The method is to approach the "realm" by first climbing up the stairs, then quickly running and jumping across the gap until you reach the other side of the bridge. From here, go through the first gate and head left to find the main entrance. Temporarily hide behind a nearby box to avoid detection by enemies.
Enter "field"
There will be three guards outside the main door, and you can take the opportunity to lurk behind a nearby chest. Once you've found your spot, aim for the head of one of the guards and knock him down quickly, then quickly take care of the other two guards as they charge towards you.
Next, a lone guard will come up from behind you, quickly take him out and then push on into the "realm". There will be no more guards in this area and you can explore several rooms on this level before heading down into the basement of the facility where you will eventually find the solder.
Find the solder
When you enter the basement of The Realm, two guards will come up the stairs. Deal with them quickly when they come into your sight. After taking care of these two guards, you'll hear two soldiers shouting loudly downstairs, meaning there are more guards at the bottom of the stairs.
Go to the end of the walkway and jump onto the large pipe on the left, then jump into the fenced-off area below so you can clear the gap to kill the remaining guards. After dealing with these guards, turn around and you'll see a bag next to some boxes. Open the bag to get some ammo, medical supplies, and food.
Continue deeper into the basement of the facility
Climb out of the fenced area, go through the open door, enter another set of stairs, and continue down a few more flights. When you reach the bottom, you'll find a guard in the hallway to your left. After knocking this guard down, several guards will run out from the other direction into your sight.
Continue to eliminate these guards, and then push into the room they came out of. You will find a few more guards inside. After quickly taking care of them, continue to move forward. There is a dark room ahead with some supplies inside. You can quickly go in and search it, then open the metal door to trigger a cutscene with the solder.
