Not yet, though it's on my list of books to read.

: There's a chapter in there on AKs in Africa.
: They were burying them in ant hills, leaving them for years, then coming
: back and pulling them out. The rifles still worked without a hitch. They
: coated them in a little oil, wrapped them in plastic, and stuck them back
: in the ant hills until the guns were needed.

Heh. Reminds me of an East German joke, where a child sees his father pouring oil on the flowerbed.
"Father, won't the oil kill the flowers?"
"Screw the flowers! I don't want the Sten to rust!"
