Thinking about 3 brothers - all SEALs - made me think of Saving Private Ryan. Spielberg based his story on the Niland brothers and the Sullivan brothers - the Sullivan story is really sad: all five brothers enlisted in the Navy (between 1937 and 1942) - they all served on the USS Juneau, which was torpedoed and exploded: they all died.

The article says there's no law preventing siblings from serving on the same ship but I wonder if it's very common.
