+The compass is a tool used to measure direction. The version modeled in ARMA is a lensatic compass with both degree and milliradian
+markings.
+**Measuring Direction**
+Typically we measure direction either generally using the cardinal directions, or more precise using degrees. Mils are not often used in
+ARMA.
+  - **Cardinal Direction:** The four cardinal directions are displayed on the center of the compass ring and allow for quick reference of general direction.
+  - **Bearing Degrees:** The inner ring of the compass shows degrees printed every ten degrees and a hash mark every five degrees. There are 360 degrees.
+  - **Bearing Mils:** The outer ring of the compass shows mils printed every 200 mils, large hash mark every 100 mils, and a small hash mark every 20 mils. There are 6400 mils.
