By any measure, Navy SEALs have had an extraordinarily prominent role in our national security over the past decade, from their sacrifices in the field that resulted in several SEALs, Michael Murphy and Michael Monsoor receiving the Medal of Honor, to the rescue of Captain Richard Phillips held by Somali pirates, to the takedown of terrorist Osama bin Laden.

And much of this has been captured in the media, from prominent movies like Act of Valor and Captain Phillips, to a flurry of books like Chris Kyle’s American Sniper, to SEALs running for office.

The Pentagon imposed a rule last September restricting the appearance of service members in video games, movies and television shows. Current and former members have widely circulated a pointed critique — titled “Navy SEALs Gone Wild: Publicity, Fame, and the Loss of the Quiet Professional” — that laments the commercialization and warns that it is doing harm.
