Im assuming you mean Outside the US,
1)Afghanistan (issue 6-7)
2)Lybia (issue 16? Is was during the whole scar-face/Dr. Venom story)
3) Brazil (I dont even remember the issue #,The Joe
team eamed up with the Oktober Guard and som Amazon tribesmen.)Also in an early issue of Special missions to get a plague antidote from a Dr Mengele wannabe.
4) Mexico (special missions 16 or 17?)
5) And of course,Scotland almost every time there w as a Destro storyline.
Fake ones that come to mind are Rio Lindo (fake Central American Banana rep.) and Trucial Absimia (fake Arab country used for a "gulf War" storyline.
