The working percentage for active duty US Army personnel who have NOT deployed to either OIF or OEF is 40 percent. There was a USA Today article a few months ago about the phenomenon, but it didn't go below the surface of the factoid to explain why this was so.

For those of us who, after two or more deployments, have met many of our peers -- some of whom were promoted over us -- without combat patches, this figure seems about right.

Perhaps they're all on permanent profile.
