This screengrab from YouTube shows a group of Swedish Marines dance and sing "Greased Lightening" form the movie "Grease."

In the small but increasingly impressive collection of military music video parodies, this new and already highly praised YouTube video of Swedish marines doing "Greased Lightnin" has got to be a contender for the top spot.

The production value along with a set that closely mimics the original — from the 1978 musical film "Grease" — make the video well worth your time.

The lip-syncing is almost exact, and the dance moves hit the beat. Well, most of the time.
