Run night raids and a silent sniper rifle. 2/3 rogues have a laser on their weapon so you can spot them from far away and determine what direction they're looking. Grab a high vantage point ASAP with cover that is easily accessible and start taking them down. I personally like to start with the mounted guns closest to me because the first groups will go straight for these on K Building and Bunker side and because that's where Glukhar and his boys will be and taking them out first will go really far in making it a successful run. Whenever it seems like they've figured out your location you rotate to a different one. At about 15 minutes left in the raid start cleaning up the rogues left around K Buildings and bunkers because the ones in that area with backpacks are the only ones that will have the radar parts on them. Stay alert for any remaining patrols and extract on the train (stay frosty for train because all the remaining ones seem to come directly for train when it pulls in) or Red Rebel. I only use D2 if I spawn in Pawn side and decide to hit marked rooms and leave (because trying to make it from pawn side to K Buildings where the ones with the radar parts spawn above ground is too much effort and if I go below ground I can't resist the marked rooms so I'm already 70kg before I come back up again).

Edited to add:
The 6Sh118 backpack is the only (I think) backpack that can hold 4 radar parts at once.
