In the first post I mentioned the 1988 book Koevoet by Jim Hooper (a US photographer / journalist based in the UK, who had embedded with SW African COIN unit, in the conflict over nowadays Namibia).

Today I found his website: http://jimhooper.co.uk/ which has a mass of photos: http://jimhooper.co.uk/gallery3.html, three short video clips and other subjects covered.

There are other books on Koevoet, notably those by Peter Stiff, a trilogy on the war(s) fought; The Covert War (2005), The Silent War and Warfare by Other means (2001). The books are not without controversy, nor cheap.
