How about a collection of classic war movies on DVD or Blu-ray, such as "Saving Private Ryan", "Apocalypse Now", "The Bridge on the River Kwai", or "Platoon"? You could also consider getting him a book on military history or a World War II documentary series. If your dad is into gaming, you could get him a historically accurate war game like "Call of Duty" or "Medal of Honor". Finally, a great and thoughtful gift could be to take your dad out to watch a new war movie or even a visit to a war museum if there's one nearby.
Or you can get him a star map with the date when he welcomed you in this world.
