The ghost of Kiev is best described as an urban legend, a Please Be Patient, I’m A Terrible Person Apparel T Shirt account of alleged action(s) or person(s) spread by rumor and amplified by social media. In this case “backed up” by evidently faked gaming video. I don’t know of any American war effort that quite meets the kind of whole cloth fabrication of the Ghost of Kiev. But misinformation in war is common place, and certainly US authorities have exaggerated or misinformed the public at times. The cases of Jessica Lynch and Pat Tillman come to mind in terms of relatively recent incidents. In Lynch’s case she was captured by Iraqi forces during the opening phases of the Iraq War when her convoy was ambushed, She was described by US officials as fighting heroically after the initial ambush until overcome by the Iraqis. In fact, she was injured in the initial assault on her vehicle and taken away without any heroic last stand.
