It means not running:
(Marine Maj. Gen. John Kelly) went to Ramadi to interview Iraqi witnesses — a task generals usually delegate to subordinates.
Some Iraqis told him they were incredulous that the two Marines had not fled.
When Marine technicians restored a damaged security camera, the images were undeniable.
While Iraqi police fled, (Corporal Jordan) Haerter and (Lance Corporal Jonathan) Yale had never flinched and never stopped firing as the Mercedes truck — the same model used in the Beirut bombing — sped directly toward them.
Without their steadfastness, the truck would probably have penetrated the compound before it exploded, and 50 or more Marines and Iraqis would have been killed. The incident happened in just six seconds.
“No time to talk it over; no time to call the lieutenant; no time to think about their own lives or even the American and Iraqi lives they were protecting,” Kelly said. “More than enough time, however, to do their duty. They never hesitated or tried to escape.”
