Cheers thats why I am testing map was a quick way of allowing.

The IEDs are stationary only change is removal of weapon & the fact can carry passengers. Its there prison cell if you like only use in the game is Prisoners unload once a freindly enters there hex & presumably frees them.
Being hard to spot is not a problem but it means prisoners cant see enemy troops while they are in it giving unfair intel.
Not usable by the AI of course.
Some blind civilians would do the trick for use as hostages.
Rules testing hostages can only move if move adj to or into a freindly units hex to represent need escorting.
