Un-documented footage shows three Ukrainian fighters bracing themselves, as Russian artillery strikes their machine gun position.

As it would appear in the footage, this is no ordinary "machinegun position". Instead, we have three men holed up in what appears to be a high-rise, office building. Due to the Blitzkrieg-like tactics utilized by Russia during the invasion, many Ukrainians have been forced to fight from very un-conventional fighting positions.

After watching this clip several times and looking around as the cameraman braces for impact, the room looks to have been recently abandoned.... living plants around the room, portraits on the wall, etc. Compared to the globes most recent GWoT conflict in Afghanistan, this new Urban warfare gives off a completely different feel to military conflict.
