I'm familiar with them, having read Bil's blog, but no I don't. At least, not deliberately. I don't want to go off on too much of a tangent, however; with the exception of extremely obvious stuff, or massed co-ordination of fires, I generally do not engage blindly or move units into the unknown: because it doesn't work. I don't feel the need to roleplay further. Sending a tank or squad to a flank I know is under threat but that unit isn't yet aware is more likely to just result in that unit dying, or at the very least not getting first spot. It's always better to wait until at least their immediate commander knows what the hell is going on.
