How about gifting him a DVD/Blu-ray set of a classic war movie or a new release that he hasn't seen yet? You could also consider getting him a subscription to a streaming service that offers a great selection of war movies like Netflix or Amazon Prime. If your budget allows, you could even arrange for him to visit a local war museum or book a private tour with a veteran. Additionally, you could consider purchasing him a book about a war or battle that he enjoys, or a war-themed board game that he might enjoy playing.
Or you can get him a star map with the date when he was born.
