What must mortar rounds be segregated by?

Mortar rounds must be segregated by lot number to ensure that munitions produced in a specific batch are treated consistently, especially considering the variations that might occur in production. The lot number allows for the tracking of ammunition, which is crucial for quality control, inventory management, and safety. By grouping rounds together by their lot number, personnel can reference safety data, inspect for potential defects, and ensure compatibility, all of which is vital for operational efficacy and safety during use. This system minimizes the risk of mix-ups that could arise if different batches were to be used together, especially when considering differences in performance, reliability, and intended use scenarios.
