What are the REAL stats?

See this article that was written on November 26, 2004:
"Seattle Times article mentions total number of amputees. According to U.S. Defense Department statistics, the more than 200 war amputees include 47 who have undergone below-the-knee surgery, 37 who have undergone above the knee surgery, and at least 14 who have lost portions of both their legs.
