Has Shock and Awe ever been used in firefighting? Probably not, as fires aren't really bothered by the psychological effects implicit in Shock and Awe warfare. But if any form of firefighting qualified for that well known military doctrine, it'd be aerial firefighting, as proven by this video of what looks like a Canadair CL-215 (we could be wrong, tell us in the comments) tackling a vehicle fire in the Canadian province of Newfoundland and Labrador.
As CarScoops points out, using a water bomber to put out a vehicle fire is like bringing a Howitzer to a knife fight, but due to the extremely isolated location of the accident authorities were concerned that a firetruck couldn't get to the scene in time to contain the blaze. Hence the airplane. The accident, involving a grader and semi truck didn't result in any fatalities, but it did close the remote Trans-Labrador Highway for some time.
Take a look at the full video below.
