Lt. Gen. Reginald Centracchio retired head of the Rhode Island National Guard gives 8-year-old David Morales a medal called a challenge coin during an appearance on WPRO-AM's John DePetro show.
I am glad to see that they did this to support the boy's patriotism.
It was a really neat thing to do.
I had to look up what a challenge coin was.
http://en.wikipedia.org/wiki/Challenge_coin
...The tradition of a challenge is the most common way to ensure that members are carrying their unit's coin...
The challenge, which can be made at any time, begins with the challenger drawing his/her coin, and slapping or placing the coin on the table or bar. In noisy environs, continuously rapping the challenge coin on a surface may initiate the challenge. (Accidentally dropping a challenge coin is considered to be a deliberate challenge to all present.) Everyone being challenged must immediately produce the coin for their organization and anyone failing to do so must buy a round of drinks for the challenger and everyone else who has their challenge coin. However, should everyone challenged be able to produce their coin, the challenger must buy a round of drinks for the group.
