From strategypage.com, this amateur video of American soldiers in Afghanistan during a mortar attack by insurgents.
The rounds are relatively few in number and the first couple are well wide of the target which is the American compound. After a few incoming rounds, the Americans start shelling a nearby hillside.
Fair warning: There is some foul language in the video. Portions are out of focus.
But just listen for the whistling of the incoming rounds.
