the old pillboxes were just pillboxes that blend in with the terrain, although once you got use to spotting them, they were easy to find. the new ones use the cloaking effect that the stealth tank uses, so they cannot be targeted unless the cloaking effect has switched off (usually because a unit is near enough to spot it)
Actually if you spot one and leave BEFORE the shroud regrows, it will be shown clear as day under the shroud. I reported this as a bug and got told to fuck off.
The fog freezes buildings in the state that you last saw them. If you last saw it while it was visible, then that will persist (even if it is then sold or destroyed).

and it should take into consideration the camp pillbox and not show it.
