How do you use an American M101 howitzer?

To use an American M101 howitzer, first, ensure the artillery piece is properly positioned and leveled for firing. Next, calculate the necessary data for the shot, including range and elevation, and set the appropriate angles on the elevation and traverse mechanisms. Load the projectile and propellant charge into the breech, ensuring the safety mechanisms are engaged. Finally, aim the howitzer at the target and fire using the firing mechanism, while ensuring proper safety protocols are followed throughout the operation.
