Digital Combat Simulator World – better known as DCS, is by far the most advanced, realistic, widely adopted home PC military flight simulator available today. While there are other flight simulators, they are either none military (ie Xplane & MsFS 2020) or they lack modern graphics and/or realism (like IL2 & Falcon 4).
There are various other videos not in category also waiting for you at my DCS channel over on YouTube
