QUESTION: u.s. military multiple deployment statistics

question / pregunta: 

from an email, identifying info snipped for privacy:

> Hey yall. This is R, who attended a few of your workshops in Detroit. I am doing research and attempting to compound some numbers. I am having a hard time finding a citable statistics explaining percentages of raw numbers of U.S. troops deployed currently and over the course of the Iraq and Afghan wars. Specifically, we want to know how many were and are deployed multiple times, and if so, how many times/what percentage served how many tours. I could only find info from 2005 here: http://usmilitary.about.com/od/terrorism/a/deploymentrates.htm
