Finishing off a sniper

The leader of the Freedom squad in Limansk, Bormann, wants you to eliminate the Monolith sniper at the [ construction site].
== Walkthrough ==
Make your way to the construction site, fighting through Limansk's natural spawns. Here's the schematic of the enemies (besides the natural ones).
After passing the ruined house, four black-suited Monolith troopers will wait in ambush behind the corners. On the approach to the site, 15 zombified stalkers will spawn up the stairs. Take care of them and move into the unfinished building.
Three more black-suited Monolithians will be guarding the building, and the sniper will be on the top floor. Be wary of his HK 417 "Sniper" as it uses highly lethal 7.62x51mm NATO ammunition in bursts.
Immediately after taking him out, you'll receive an invitation from Sviblov for the quest Serious Talk.
Return to Bormann for some ammunition and another task.
== Notes ==
* Bormann's dialogue mentions the "Construction Site" in capitalized letters, but he's referring to the unfinished building in Limansk and not the separate zone itself.
* There is a large amount of 5.56x45mm ammunition in Limansk, as well as many enemies using it, so clearing out the area with a weapon of that caliber will let you go positive on ammo.
* Bormann says that they managed to reach Limansk in a squad of 5, but there's at least 13 Freedomers in Limansk, including himself.
