How about a collection of classic and iconic war movies? You could choose some of his favorites like Saving Private Ryan, Black Hawk Down, and Full Metal Jacket, as well as some lesser-known but equally compelling films like Platoon, The Hurt Locker, and Dunkirk. Alternatively, you could get him a book about his favorite war movie, or even a historical book about a specific war - perhaps something about a battle or campaign he's always been interested in. Another idea could be a visit to a nearby military museum or reenactment - this could be a fun and educational experience that he's sure to enjoy.
Or you can get him a star map with the date when he was born.
