Advice on Pillboxes

[Banquet]

Is there a way of treating pillboxes accurately in COTA? I've thought about making them fortifications but as they were often only manned by 3-4 people plus a MG it becomes difficult on a Company scale sim. Is there a way of abstracting them that works?

My best workaround at the moment would be to make a long, thin fort and put a company on it at max frontage to simulate some kind of defensive barrier. Problems resulting are it might be easier for the enemy to occupy and receive a defensive bonus for than a series of pillboxes would be. Also, there would be less opportunity for ambush/bypass, etc.

Are there any other options I'm missing?
