What was the solution?

So if I understand correctly then with the IED module the intended function is to either be unlinked or linked to a Asymmetric force, and if unlinked it only places IEDs not suicide bombers or VIEDs?

With the roadblocks I only see them from the asymmetric force, the occupying force is not placing them. The map used is Takistan.

I think my problem was that I am not using an asymmetric commander at the time. I only wanted an Occupying force.

I added an Asymmetric commander and set him up with a few placement modules and tested that. Just to be clear I have been using the debug option and going around the map checking different areas

I have come to find the following:
IED Module - if linked to Occupying force it dose not place IEDs other than a rare occurrence

• if linked to Asymmetric force I have not seen it place yet but I have not tested it extensively
• if unlinked it places IEDs fine other than some wacky locations, car bombs place, no suicide bombers

Roadblocks - Occupying force, does not place them. It should but it does not.
- Asymmetric force, does place them in the small areas they occupy.

I get IEDs but never once have I seen a suicide bomber. So I as well would be interested in some light being shed on this topic.

It may be worth noting that I also have issues with roadblocks poping up. I get zero and have tried the roadblock option in the Military Placement CO module and have not seen a single roadblock. Is it a problem with maps other than the default arma maps?
