What is the purpose of illumination rounds fired from a mortar?

The purpose of illumination rounds fired from a mortar is primarily to provide light on the battlefield for enhanced visibility. These rounds are designed to create a bright light that illuminates the area, allowing friendly forces to see their surroundings more clearly during low light conditions, such as at night or in overcast weather. This enhanced visibility can significantly improve situational awareness, allowing troops to assess the battlefield, identify potential threats, and coordinate their movements more effectively.

While other options may involve tactical elements on the battlefield, illumination rounds specifically focus on improving visibility rather than offering direct support or communication functions. This function plays a crucial role in operations where visibility is limited and can greatly impact the overall effectiveness of ground forces.
