How about gifting him a collection of war movies on DVD or Blu-ray? You could also throw in a subscription to a streaming service that offers a selection of war movies. Another gift idea could be a book about his favorite war movie or a biography of a notable military figure. If he enjoys playing video games, you could gift him a popular war-themed game or a gaming mouse, keyboard, or controller that incorporates military or camo designs. Finally, you could gift him a replica of a weapon or a poster from his favorite movie or WWI/WWII.
Or you can get him a star map with an important date you share.
