The impact on the base was expected to happen at 2.30 a.m. on February 18. During this time, as the Russian blogger on the Telegram says: a combat alert was announced, marked as “an enemy attack on land”. Shortly thereafter, the operation was to start the short-range air defence strategy Pancyr S1. The Russian strategy or systems were expected to drive intense fire for an hour. Pancyr was then to “work” but with little intensity.
