Texasgurl,
If you had anyone in your family who served in the military in the 1960's or 1970's, you would know that there was a massive fire which destroyed a large quantity of the military records from those eras. When my father retired at age 65, he had a horrible time getting his social security benefits done properly because the government claimed the records from that era had been destroyed in a fire. If he had not kept some of his own records and remembered his ID number from the Army, they would have had a hard time verifying his service. Go talk to someone who was in the Army and recently retired, they'll confirm this.
