ghost
n.— «What was meant to be a day meeting the Iraqi people in one of Baghdad’s eastern neighborhoods abruptly turned into a long day of what the soldiers now refer to as “chasing the ghosts of small arms fire.” The troops used to laugh about these “ghosts” and their poorly aimed potshots, but now they take them very seriously.» —“Soldiers in Baghdad chasing ‘ghosts’” by Arwa Damon in Baghdad, Iraq CNN Oct. 6, 2006.
