The Department of Defense classified Catholics, evangelicals, Jews and Mormons as religious "extremists" in military training materials, according to the Chaplain Alliance for Religious Liberty.
More than 1,500 pages of documents were just released to the chaplain group under the Freedom of Information Act.
"Many extremists will talk of individual liberties, states' rights, and how to make the world a better place," Newsmax quotes the study guide.
Trainees are warned that involvement with "extremist" organizations is "incompatible with military service and is, therefore, prohibited."
The documents also show that the military considered the Southern Poverty Law Center's "hate group" list as a "reliable source."
"The U.S. military violated its appropriate apolitical stance and engaged in a dishonorable mischaracterization of multiple faith groups," Ron Crews, executive director of the Chaplain Alliance, told Fox News.
Tom Fitton, president of the conservative watchdog group Judicial Watch, shared Crews' sentiments.
"It's disturbing insight into what's happening inside Obama's Pentagon," Fitton said. "The Obama administration has a nasty habit of equating basic conservative values with terrorism."
