Asked and answered. You arent doing a good job warming up your car. All you are doing is wasting gas, and increasing wear. If you wanto get into a warm car, so be it, but dont think you are doing the best thing for the car by idling it like you are. You are doing more harm then good.

As 98 said, you probably drove a diesel in the army. A gasoline engine is another animal, and doesnt need to warm up like diesels do.
