I also spent a long time searching for open sources and found the website
https://thechronicles.online/en/explore , which publishes videos directly from combat zones. There you can see footage of artillery, tanks, aviation, and even civilian evacuations in different countries. I liked that the videos are divided into categories, such as Drone Warfare, Frontline Combat, or Civilians & Evacuations, so you can quickly find what you're interested in. This gave me a better idea of the scale of the conflicts, showed me the real consequences of shelling, and helped me understand how war affects the civilian population. The service is very clear and allows you to get information quickly, without political embellishment or censorship.
