The Croats certainly had and used the Milan, and the Afrikaners certainly had them.
There are several generational differences between early and later model Milan missiles, and a late or developmental model Milan warhead is at least a possible suspect. And the use of a Milan launcher is consistant with with some of the reports of Abrams taking hits from weapons mounted in the back of light trucks during the sandstorms during the early days of clearing the Iraqi cities.
Metalurgical evaluation of the recovered penetrator slug will tell the tale. We'll see.
