Portraying the military on TV

One thing that really makes me want to switch TV channels instantly (there are many more reasons for sure) is when I watch a TV series (like the other night when I watched Cold Case on CBS) and there are actors playing a military individual, and they wear totally incorrect uniforms or items that go along with it. Qualification badges, achievement ribbons, rank insignia, and so forth. Actors typically selected to play a military person also always seem to be way too old for the rank they are wearing, are too fat, have hair that's way too long, and in sum look nothing like a "real" military person. Lastly, there seems to often be a tendency to have the actor portray the military person in a manner that reminds me of the late 1960's when anything "military" was a bad thing.
