If you had a choice, which uniform pattern/style would you want to wear?
So although I understand the desire, the fact is a common camo uniform doesn't make much sense. Maybe instead of defining uniforms by service, we could have a common utility uniform and then regional tactical uniforms for training/deployment. This to me would make more sense. A simple OD, Navy Blue, black or whatever utility/cover all/ whatever you want uniform for day to day duty and non-combat deployed folk, and then battle dress defined by region for when/who needed.
You will never be wearing the same stuff in Kawait as Korea, so why bother defining a common cammo pattern for everyone everywhere to begin with?
The Coast Guard over the last ten years has toyed with its utility uniform for strictly CG missions but whenever we deploy with our sister services, we simply adopt whatever they wear for the duration. To me, it would make more sense if there was one (don't care what) uniform for all services with the primary influencing factor being it's functionality in the environment. That might mean having one uniform for green
environments; another for brown ones; another for urban areas....but certainly a common uniform for everybody based on application, not on service.
Think about the savings, and the simplicity for identifying friend from foe. I read an article recently about a multi agency police shooting. One of the issues that came up during the debrief was that the agencies involved all had different uniforms and it caused some confusion about who was law enforcement, who was EMS, who was a bus driver just caught in the line of fire....something to consider.
