Kaz tasks you with killing two targets in this mission, Glaz and Palitz. For this achievement, you must extract both of them rather than kill them.

Isolate the targets from their two bodyguards and tranquilize them with the Wu Silent Pistol. From there, transport them to a safe extraction point and call in the helicopter.

When you start out, Glaz is way up in the watch tower at the Admin Building (Paz was located in the rear underground portion of the Admin Building during the main mission). Palitz is usually just south of Glaz roaming around an open area near some warehouses. However, by the time you take care of Glaz, Palitz will shift his position (or vice versa). Try to locate and mark both of the targets with the binoculars first before making the move on one of them.

Kaz will update your map on the iDroid that reveals the general location of where the targets may appear if you lose track of them. Stay alert and listen to Kaz’s notifications.

Here's an image of the two. Glaz on the left, Palitz on the right.
