This is the Norwegian Royal Guard Regiment (equivalent to the British and Canadian Guards regiments). These guys give the USMC Band and Honor Guard and the Army's 1 BN 3d Infantry (The Old Guard) a run for their money. It is interesting how a cheesy Hollywood theme (from "The Good, The Bad, and The Ugly") can sound impressive when played by an elite military band.
This is "River Dance" with boots and rifles! I can't remember ever seeing a display of precision to beat this!!
All the precision drill is being performed on ICE!!
Those are US made Garand M-1 rifles (WWII), and they are heavy weapons (9 POUNDS EACH).
When that one fellow goes on his own - YOU'VE NEVER SEEN A RIFLE SPUN THAT FAST!
