Greek S-300
Greece has the S300 deployed on Crete. They weren't the originally intended customer as the missiles were being purchased by Cyprus. However, the local bully boy (Turkey) declared that deployment of the S300 system on the island would be considered as an act of war. I believe the original purchase was pay rolled by Greece and they took delivery when it was agreed that Cyprus couldn't have them. Just another example of how Turkey ought not to be part of NATO, they have entirely different values and standards to the majority of NATO nations.
