Maybe, but not in the way you expect.
Say we go to another African nation for peacekeeping or whatever, and say that nation was a colony of either France, UK, Belgium, Germany, Italy...you get my drift.
If I were the one picking candidates (I am not), maybe a thought would be "would the local population be more receptive to a white or black dude", all things being equal (e.g. they both speak the local lingua franca, etc). I would probably be considering that even more if it's not under the auspices of something like the UN.
Taking it further - same goes with women. I wasn't doing that, but I've heard that in Afghanistan, having female soldiers/etc on patrol meant that they could talk to the women, whereas generally the men could not. That gives an entire new aspect to the situation and yeah, I'd probably want to make sure that the task force includes women.
