Tanks in a defensive position were often dug into an emplacement in order to provide them with extra protection. Emplacements provide no +TM but all hull hits against a tank under an Emplaced marker are negated, and the targeted tank does NOT have to take a Morale Check. Tanks under an Emplaced marker can only move out of the emplacement by reverse movement into one of the three rear hexes. Once a tank has moved out from under an Emplaced marker, the marker is removed from the Map. If an Emplaced tank is destroyed, replace the Emplaced marker with a Wreck marker. Emplaced tanks need not be spotted unless required by the other terrain in the hex.
