Ukrainian Drone Enthusiasts have been volunteering drones and expertise to help repel Russian forces.  I reached out to Denys Sushko, Head of Operations in Kyiv-based DroneUA, to dig deeper into this story.  Denys sent several pictures and videos that document the efforts of the drone industry to support Ukraine during this conflict.  If you want to further support these efforts, Denys provide the following links for anyone that wants to donate drone equipment or help fund humanitarian missions in Ukraine:
