Islamic Republic of Iran Navy
It is charged with the responsibility of forming Iran's first line of defense in the Gulf of Oman and beyond with the mission of acting as an effective blue-water navy. However, it is generally considered as a conventional green-water navy as it mostly operates at a regional level, in the Persian Gulf and Gulf of Oman but also as far afield as the Red Sea, the Mediterranean Sea and northwest quarter of the Indian Ocean. In July 2016, the Navy said that it would establish a presence in the Atlantic Ocean, of unspecified duration.
List of ancient Iranian peoples
Ancient Iranian peoples lived in many regions, and they had as farthest geographical points dwelt by them: to the west the Great Hungarian Plain (Alföld), east of the Danube river, and to the east the Altay Mountains western and northwestern foothills and slopes, western Gansu and even Ordos in northwestern China, to the north southern West Siberia and southern Ural Mountains/Riphean Mountains and to the south the northern coasts of the Persian Gulf and the Arabian Sea. The geographical area dwelt by ancient Iranian peoples was therefore vast (at the end of the 1st Millennium BC they dwelt in an area of several million square kilometers or miles thus roughly corresponding to half or slightly more than half of the geographical area that all Indo-European peoples dwelt in Eurasia).
