It is noted that S-300s have been deployed on the eastern tip of Crete for the last 22 years and patrolling an area within a radius of 280 km around the island.

Their first practice sessions took place at a NATO training ground in western Crete in the suburbs of Chania on 13 December 2013, 14 years after they were deployed in Crete.

Since then, there has been no shooting.

Earlier in the Astrakhan region, a field exit of troops with the participation of S-300 complexes took place.
