Ukrainian flag of the 79th Airmobile Brigade mortar battery In November-December 2014, the "Tsunami" battery secured position in the village of Pisky not far from Donetsk. Commanders who defended the Donetsk airport - the renowned "cyborgs" - signed the flag in a newly fashioned tradition as a sign of gratitude to the mortar operators for their fire support. This flag accompanied troops throughout their long combat path from Mykolaiv to "Dovzhansky" checkpoint at the Ukraine-Russia border, and later from Krasnyi Lyman to Mariupol.
