QPME: Marines in Pearl Harbor

Of course they had already started taking out the machine guns. They didn't wait for the key in the OD's office, they just broke the door down and hauled out the machine guns, put them in position. Everybody that wasn't involved in that drill grabbed their rifles and ran out in the parade ground, and started firing at the airplanes. They must have had several hundred men out there with rifles. And every [Japanese] plane that was recovered there, or pieces of it, had lots of .30-caliber holes — somebody was hitting them, machine guns or rifles.
