What is the purpose of "field expedient" adjustments in mortar operations?

The purpose of "field expedient" adjustments in mortar operations is to adapt quickly to dynamic battlefield conditions. In a combat scenario, situations can change rapidly due to enemy movements, terrain features, or unforeseen obstacles. Field expedient adjustments allow mortar crews to make immediate and practical modifications to their firing procedures or equipment to maintain effectiveness and accuracy in these changing circumstances. This flexibility is crucial for responding to threats or targets that arise unexpectedly, enabling the unit to remain operational and effective under pressure.

The focus on speed and adaptability is essential in warfare, where every moment counts, and the effectiveness of fire support can significantly impact the outcome of engagements. Therefore, the ability to implement adjustments swiftly without extensive equipment overhauls or delays plays a vital role in mortar employment strategies on the battlefield.
