The only theater it would have probably been deployed is Iraq, and early Iraq, like 1991 during the first Gulf War. The USMC probably had them as well when they started GWII, but I think they would have had the updated wheels and tires (more like what you would see on a CDN Coyote or my LAV-C2, will wider tire).

Afghanistan....I don't think they would have any deployed there, as there would be no point, I could be wrong however, but the Taliban don't have too many tanks to use. I know Canada deployed some of the their TOW optics just for the sake of them being superior optics to use to look into the mountains, but they were never deployed with live missiles with the CDN launchers.

Just did some reading, and apparently some LAV-ATs participated in the big tank battle at Kafji during GW1, your kit fits the bill for that.
