The United States armed forces cannot recieve cards to "any serviceman" this year due to fears of terrorism. Instead, the Pentagon has set up a secure email system that allows anyone to send a message to "any serviceman." Just pick the branch of the service, type your message and click send.
The story behind the "to any serviceman" cards:
Since 1967, when Sgt. Billy Thompson wrote Abigail Van Buren and mentioned that a wonderful Christmas present to our armed forces would be "just a letter from home," American citizens have been sending holiday wishes to servicemen and women stationed overseas every holiday season. Dubbed "Operation Dear Abby," the program has brought holiday joy to hundreds of thousands of U.S. military personnel deployed away from home.
