What Happens If You Fired Tank Gun in Space?!
When a tank fires in space, it works due to self-contained propellant, the shell travels in a straight line indefinitely, and the tank and gunner experience a recoil in the opposite direction. The specific path of the shell and tank depends on the location: near a planet or in Low Earth Orbit (LEO), the shell will eventually be captured by gravity, enter the atmosphere, and likely burn up, while in deep, empty space, the shell will travel forever until it hits something.
