This is the echo of war.

A woman with closed eyes appears in a close-up, followed by a man in a black cap and face covering, then a close-up of a military patch, a soldier in a helmet and mask, a group of soldiers in a dimly lit tunnel, and finally a soldier standing on a tank in a snowy landscape. The sequence shows a series of military-themed images with Russian text overlays, including "серый туман" (gray fog), "обнимает мосты" (embraces bridges), "в ушах стоит звон" (a ringing in the ears), and "это эхо войны" (this is the echo of war), set against a backdrop of military personnel and equipment.
