How to unlock the Supportive Staff achievement in Control - Definitive Guide
You can get the 5 kills over multiple rangers and still get this achievement, but it possible to get all 5 in the room after the desk pictured. The ranger AI isn't very good so you'll have to whittle enemies down to little health and wait for the ranger for eventually kill them.
Fast travel to Warehouse, head south into the tunnel to find the radio station. Radio for a ranger to be deployed to you and then had back into the warehouse area to make enemies spawn. Try to chip the enemies down to low health and use your shield to distract them while the very bad Ranger AI tries to kill them.
The 5 kills can be across multiple rangers, so just summon another one as needed.
One ranger doesn't need to get all 5 kills, just has to be 5 kills total from any ranger.

After completing "Complete the Ritual in the ...", Emily Pope will arrive at the Nail where you got your Foundation powers. Speak to her and she'll tell you that Rangers are available to help when called on. To call one in, just head to a radio comm station and hold . To get the Ranger to successfully get a kill, lower the enemies' health then let the Ranger kill them. This doesn't have to be done in one Ranger spawn as it is accumulative.
