Which unit range is not matched with a Major's designation?

The correct unit range that is not matched with a Major's designation is the range of units from 4000-4099. This range does not align with the designations typically assigned to a Major, as unit allocations often follow a specific structure based on the rank and operational responsibilities within the department.

In standard practices, units designated for a Major usually fall within specific series that can reflect their level of command or the type of operations they oversee. The ranges specified for the other choices align with established designations, indicating units that typically report directly to a Major. The 4000-4099 range does not hold these designations, which is why it is identified as the outlier among the other provided options. Understanding unit ranges is vital for keeping track of command structures and responsibilities in any dispatch or operational setting.
