The test range is within the Crimean territorial sea according to Russians, who claim the Crimea, while Ukrainians say they'll be testing within their territory. It's air-to-air missiles that are to be tested, therefore a flying target must be on the scene. The situation might be a who-strikes-the-target-first contest.
We'll learn it today or tomorrow.
Do you have a map locating the test range? The one I saw showed it well west of Crimea. But maybe that is incorrect?
