I have one of the Service Connected cards from the VA so I probably would not bother. However I do think it is a good idea. As for being on someones "list" I'm a Veteran, have a CCW card, have a C&R FFL, I had a Secret clearance in the Army, I'm a Deacon in my Church and Commander of my American Legion Post. Besides, I hang out here so I'm sure I'm already on someones watch list.
