There are sixteen military athletes competing in the Olympics this year, and a few military family members as well. As one might expect, shooting events are well represented, but so are others like fencing and track and field. Here are a couple of good sites that focus on the military Olympians.
If I have read the press releases correctly, the U.S. military (including family members) has won two gold medals and one bronze..and they’re not done yet. There are more events planned later this week in which the military will be represented.
