I will try and give you a couple of examples of why grooming( which includes tattoos), military bearing, manners, and intelligence is important in today's military. Prior to and during WWII enlisted personnel were basically seen as crude, unintelligent, and a few other unflattering terms, this attitude continued for a few years and slowly changed. In 1966 I was waiting for my next command to return to port in the Philippines so that I could report aboard. A group of us were told to report to a building, upon arriving we were individually talked to and basically screened. I along with a few other enlisted sailors were told that we were being assigned to special duty. We were given a cash allotment and told to purchase presentable civilian cloths. We were then taken to Manila and each given individual rooms at one of the finer hotels. We were to be assigned as liaison for transportation of reporters, officials, and other dignitaries attending the Manila Conference. President Johnson was also attending the conference. During this period of time I and the others were direct representatives of the US and I would say that most of the people we interacted with knew we were members of the US military. Jump forward about 12 years, we were in Papua New Guinea. The ships officers and senior enlisted were invited to attend an informal luncheon, in uniform, hosted by the US Ambassador to New Guinea. Needless to say we were representing our country, and the US Navy. Appearance was only one of many attributes that we had to present. During my military career I had other opportunities to attend other events of this nature. Now I am not saying that tattoos mark you as uncouth or not presentable in society; However, your appearance and overall military bearing definitely reflects on your country, your service, and yourself. Look at those that are walking post at the Tomb of the Unknown Soldier. What would the opinion be of visitors that saw one of these guards with a visible tattoo?
