Libya.
Beirut/Lebanon.
Edited to add:
Two VERY large items that will be missed if you don't explicitly include them, but are SO large that they have had a profound effect:
1. The Cold War! There hasn't been a RAF airfield in Germany for years, but it used to be the frontline.
2. Annual spending rounds.
