What is the rate of descent for M485A2 illumination rounds?

The rate of descent for M485A2 illumination rounds is correctly identified as 5 meters per second. This rate is significant for understanding how quickly these rounds fall and the time it takes for them to reach their intended target or area of illumination. Knowing this rate allows operators to plan and adjust their fire support accordingly, ensuring that the illumination provided meets operational requirements and maximizes effectiveness during nighttime operations. This information is essential for coordination with maneuver forces and optimizing the overall mission effectiveness. Other rates do not accurately reflect the operational capabilities or performance metrics of the M485A2 illumination rounds.
