Helmet camera footage released by a member of the Ukrainian Foreign Legion shows several intense gunfights against Russian forces in the city of Severodonetsk.

Urban warfighting is an absolute nightmare. At all times, you are in a fully 3-Dimensional threat area. Every window, every doorway, every rooftop and every street corner is a potential danger area. During military operations in urban terrain, the individual warfighter has an incredibly limited scope of situational awareness, and without clear lines of communication battles can often turn into absolute chaos. We're not seeing that absolute chaos in Severodonetsk however.

In the video above, we're watching a team of fighters from the Ukrainian Foreign Legion as they maneuver through the buildings and streets of Severodonetsk. Their opposition is the Russian military, not a group of armed insurgents, but an actual professional fighting force with the might of an entire nation standing behind them. Both sides of this conflict are armed with all of the weapons and equipment of first world military super powers, and both sides are comprised of trained professionals specifically intent on ending the lives of their opposition.

Questions about the competence of the Russian military aside, the guys fighting in this video are all trained professionals, regardless of how you might feel about the situation. No one involved in these firefights are untrained goons haphazardly spraying their rifles with the sights set to 11 because "it makes the rounds more powerful." You're watching fully trained and experienced warfighters shoot nose-to-nose against one another. This video might be one of the best clips of modern warfare that has ever been recorded. It's certainly one of the greatest pieces of combat footage that I have ever seen, and I've been documenting combat footage for the past seven years of my life.
