What is the general rule for map reading?

The general rule for map reading that involves determining directions and orientation is "Up then Left." This means that when reading a map, one typically starts by aligning the map with the direction they are facing, which is usually upwards on the map, or North. Subsequently, movement or navigation may involve focusing leftward from that point if necessary.

In this context, your choice of "Right then Up" does not align with the established practices of map reading, as the foundational direction is typically to look upwards first, indicating North or forward position, and then determining lateral movement as necessary. The understanding of basic map orientation is crucial for effective navigation and communication among military personnel.
