Competence in pattern detection is pretty much an IQ test. When you go higher on the scale, the number of non-whites, non-asians, and non-jews drops precipitously. I wouldn't bet my house on this prediction, but I would bet a few hundred $. For one, maybe the competence required is not that high. But you are surely wrong about Special Forces. They are overwhelmingly white. See here: http://e-ring.foreignpolicy.com/posts/2013/05/10/budget_watc...
