It's an annual tradition, and what some call the greatest rivalry in sports: Army vs. Navy.
The Naval Academy has emerged victorious for more than a decade straight, but that track record doesn't mean much to either team heading into this month's match-up in Philly.
The game will be played Dec 14 at the same stadium where the Philadelphia Eagles play their home games.
Each year, Cadets and Midshipmen make 'spirit videos' to poke fun at the other academy and its team, as a way to add fuel to the fire of the rivalry.
In the end, we're all on the same team, but man -- during that game, both sides wants to hammer the other team into the ground.
