What does CHG signify in artillery operations?

In artillery operations, "CHG" signifies "Charge," which refers to the amount of propellant used to propel the projectile from the gun. The charge is critical as it directly affects the range and trajectory of the fired round. When calculating firing data or making adjustments during artillery operations, knowing the specific charge that is used is essential to ensure accuracy and effectiveness in hitting the designated target.

Understanding the term "charge" is vital for safely operating artillery systems, as different types of ammunition may require specific charge settings to achieve optimal performance. The other terms, while they may relate to various aspects of artillery operations, do not capture the specific meaning of "CHG" in this context.
