Russian Armed Forces V2

A soldier in full combat gear moves cautiously through a dimly lit, damaged interior, then the scene shifts to two soldiers overlooking a war-torn urban landscape from a ruined building, followed by soldiers advancing through a smoky, debris-strewn environment, a lone figure walking into a dark, rocky tunnel, a distant explosion sending a plume of smoke into the sky, and finally a soldier in a camouflage uniform and face covering standing in a trench.
