Your “guess that special ops mirrors ...” is incorrect.
The breakdowns are available. A simple Google of “racial breakdown of special forces” yields a first link to a >100 page Rand report from 1999 detaling everything you would need to know to answer this question intelligently. Link follows:
Blacks are 2-4% of officers and enlisted in SEALS, Special Forces, and Rangers. POINT of the spear - UNDER represented by factor of 3. I believe - numbers have increased to where they are more 6%-2% now. Under - by 2.5X.
Test results etc are part of the report.
There is no need to guess, or argue, over a fact that can be looked up.
That report was in 1999, it’s 2012 now. It really does not matter, special forces are just one component of the military services. It takes a whole lot of support to even put a special forces unit into action.
Almost all minorities are under represented in special forces.
