Brooks & Dunn -- on their way to a performance for U.S. Navy and Marines personnel -- were diverted to the Pentagon to receive a special surprise.

The duo met with General James L. Jones, Commandant of the U.S. Marine Corps under heavy security. "The Commandant presented us each with a silver chalice and a Commandant's Coin, which he presented with a handshake. These coins are quite the coup in the inner circles of the armed forces and secret divisions of government, so it's quite a big deal to be given one." The coins are part of a special military tradition known as "coining," where the last person to toss their coin at a bar or restaurant buys the drinks or dinner.

This is the second time Kix and Ronnie have been coined -- they were previously presented with coins from the Presidential Protection Division of the White House. Just in case, Ronnie brought this coin with him, explaining, "I don't mind buying dinner, but I don't want it to be because I missed a step. So I always keep mine with me when I'm in the D.C. area."
