Should the services go back to a standardized battle uniform?

There has been recent discussion on AFN about designing and developing a new patter for all services to wear.  I personally feel that a unified uniform is a fine idea, however, designing a new pattern seems wasteful.

Since the implementaiton of OCP patter, and all related gear, why not stay with that pattern.  All other branches, except the Marines, wear the OCP while deployed.  Undoubtedly there are stockpiles of OCP at vairous CIF locations across the country, and all things considered, the OCP uniform is a good looking pattern. 

By implementing use of OCP as the standard battle dress uniform across all branches of service, not only would we as a military gain an unified appearance, but tax dollars could be saved by not designing and fielding an all new pattern with all new gear. 

The OCP pattern is readily avialable, has a proven track record, and requires little in way of fielding as it is already in play.
