Concerns about white nationalist groups were more pronounced among minorities in the ranks. Nearly 42 percent of non-white troops who responded to the survey said they have personally experienced examples of white nationalism in the military, versus about 18 percent of white service members.

When asked whether white nationalists pose a threat to national security, 30 percent of respondents labeled it a significant danger, more than many international hot spots, like Syria (27 percent), Pakistan (25 percent), Afghanistan (22 percent) and Iraq (17 percent).

But a notable number of poll participants also bristled at the assertion that white power ideology is a real problem.
