For those interested the book IGOR ZHDARKIN - WE DID NOT SEE IT EVEN IN AFGHANISTAN is worth a read to see events through the eyes of a Russian translator/advisor during the Angolan war. (Above the photo of the book cover is a link to a word doc - We did not see it even in Afghanistan.doc - website is in Russian.)

There is a review to be found here

Two quotes from the review:

"As the author relates, even the Russians who had served in Afghanistan had never experienced such “horrors” as the barrage of SADF artillery across the Lomba River. Under fire from the G-6 guns and the Mirage and Buccaneer aircraft, FAPLA brigades panicked and deserted the field in flight, leaving behind their Soviet equipment in a graveyard of tanks, trucks, ammunition, and other materiel. "

and

"As for the Angolan soldiers, they were “unsuitable for war.” Not only were they “afraid to take part in combat actions,” they were also unwilling to follow the “reasonable advice” of their Soviet advisors (p. 341). Consequently, it was necessary for the advisors to tell the Angolans that they were wrong and beat them up accordingly."
Fabulous stuff... the Keystone Cops in Africa.

Note: The G-6 is a 155mm SELF-PROPELLED GUN-HOWITZER
