What does the abbreviation MVS stand for in artillery terminology?

The abbreviation MVS stands for Muzzle Velocity Sensor. In artillery, the Muzzle Velocity Sensor is a critical component that measures the speed of a projectile as it exits the muzzle of a cannon. This information is vital for accurately calculating range and trajectory, which directly affects the effectiveness of fire support. By providing real-time data on the velocity of the round, the MVS helps artillery crews make the necessary adjustments to ensure precision in targeting.

The other options provided do not accurately represent the functions or terminology associated with artillery operations. Muzzle velocity is a specific term that distinguishes it from other types of sensors that may focus on different aspects of motion or measurement in various contexts. The focus on the muzzle indicates a direct connection to the cannon's firing process, making it essential for achieving accurate fire missions.
