A unit of Swedish Marines stationed in Afghanistan recreate the "Greased Lightning" dance sequence from the 1978 movie Grease. Instead of a hot rod, they are paying tribute to some kind of jeep, but you gotta work with what you have! I think they did a wonderful job. You may want to compare their choreography to the video from the movie. Eddie Deezen's not in that scene, but you can see his role here. -via Tastefully Offensive
The jeep is a South-African BAE RG32 Scout in a special Swedish arctic/desert version called Galten (the boar).
