I noticed that at least in PvP Dubno, the russian demolition charges do not work in cities. They are supposed to destroy "infrastructure and roads" but the damage is instantly repaired. Also, it doesn't work on airfields. I tried it in a couple of towns, not just primary VP. They make a nice detonation and throw smoke and debris and make smut and potholes but roads are still passable and I'd like to be able to destroy them.
