What is the purpose of the white line on the clamp handle assembly?

The white line on the clamp handle assembly serves as a critical reference point, ensuring that the assembly is positioned correctly when the mortar is set up. By indicating that the clamp handle is skyward and centered, it helps the operator achieve the correct alignment and orientation for effective firing. This correct positioning is essential for accurate targeting and stability during operation. The visibility of the white line allows for quick checks, helping to prevent errors that could arise from improper handling or misalignment of the equipment, ultimately ensuring the successful deployment of the mortar system.
