How to unlock the Debriefed achievement in Sniper Elite 4 - Definitive Guide
Mmkay, that SE 4 update fixed this apparently.
There are five officers that you must kill all at once. They are all located in a lecture hall auditorium in one of the university rooms with a chandelier right above their heads.
Enter the town by climbing the yellow pipe, which is the secret entrance along the northwestern wall (refer to Fish in a Barrel for its location). Follow the path moving east until you reach the outer wall of the university. Kill the enemy patrolling (he might be sitting down) and continue. When you exit from the next tower, there may be some enemies patrolling. Kill them and proceed to the left into the university building's open door
Once inside the hallway, turn left follow the hallway and then turn right (in front of the stairs) in the first room stay crouched look up and shoot the chandelier. Alternatively, you could follow the path as in the video, in which after entering you would turn left and then left again and walk up two flights of stairs. Straight ahead to the left is a doorway on the right. This is the lecture hall auditorium. Whichever method you use, make sure to check your radar to ensure that all of the indicator dots are all bunched together. They will be directly under a chandelier. Shoot the chandelier where it meets the ceiling and it will fall on all five officers. Make sure that you get credit for a ‘Multi-Kill’ and that five officers were killed. If you are successful, the trophy will pop.
Here is a useful video thanks to bLaKgRaVy:
Note: if you happen to complete other objectives before making your way to this room, the officers will probably not be all bunched together. It is recommended that as soon as you start the mission you get this out of the way first.

Enter the town via the secret entrance along the northwestern wall (refer to "Fish in a Barrel" for its location). Follow the battlement moving east (there is a sniper along the way) until you reach the outer wall of the university (you will go through two towers after the sniper). Kill the enemy patrolling (he might be sitting down) and continue. When you emerge from the next tower, there will be three enemies patrolling.
