I've been running around doing an insurgency mission for a couple days now and have yet to see an IED. All the modules are set up correctly, I just haven't been near their commander module so maybe it's all concentrated there?

Believe it is OPCOM debug. I've also found them to be extremely rare. "Most" I ever saw was 2 got placed after the server ran for 6ish hours, starting installations were extreme, they started with a lot of troops and was before the update that slowed down progression.

Hopefully a bug, or the threat level could be used to make the OPCOM order more placed.
