At Arlington, soldiers from almost every American war and military battle are buried there, including well known leaders such as General George S Patton.
Some well know movie legends who served in the military are buried there, including Lee Marvin, Charles Durning, and Jackie Cooper. Also buried there are actresses Constance Bennett and Phyllis Kirk, whose husbands were veterans.
I did not have a chance to visit all of their graves (that might have taken all day to do), but I did see the grave of Audie Murphy, who was the most decorated soldier in WWII, and also acted in the autobiographical film of his life To Hell and Back.
Some Presidents of the US are buried there including John F Kennedy. I got to see his grave; next to it is an eternal flame. Nearby his brothers and father are buried there as well. Here are some additional photos.
Overall it was a very emotional and inspiring experience, and I recommend everyone visit if they are ever in the area. Plan for at least a half day or a day, and plan on lots of walking!
