OffDutyGamers.com is a gaming site specifically targeted at military veterans. Here is how they think of themselves in their own words:

This site is for all the active duty military and prior service veterans who enjoy video games and the associated hardware but are easily annoyed with throngs of civilian ‘experts’ who seem to know more about the ‘military’ portion of today’s games than an experienced member of the military. This site is about delivering all the same news, reviews and sense of community coupled with our collective bond of service and unique point of view. This site is primarily for veterans, by veterans and aims to support our community.

The site reviews military games and is a meetup for military personnel who want to play online with other services members.
