Non car il faut dévoiler momentanément pour prouver que c'est bien une unité réelle (et non un Dummy)
A12.14
If the only Good Order enemy ground unit in LOS is itself concealed when a concealed friendly unit makes a concealment-loss action (other than breaking or being Reduced/Wounded), that enemy unit must completely forfeit its "?" momentarily (to prove that it is not a Dummy) if it opts to force the friendly unit to lose his; the viewing unit's momentary forfeiture of concealment is instantly regained.
