Terminal Learning Objective:
Marine Option Naval ROTC students will identify terrain features and plan a land navigation route using a 1:50,000 scale navigation map, a protractor, and map pens/markers
Enabling Learning Objectives:
Identify marginal information on a map
Identify the
terrain features on a map
Determine grid coordinates on a map
Measure straight-line distance and azimuth on a map
Calculate pace count

DETERMINE GRID COORDINATES
Select the correct scale on the protractor.
Place the horizontal scale on the grid line with the “0 mark” at the lower left-hand corner of the grid square.
Slide scale right until the vertical scale intersects the center of your plot point.
Read right then read up

Slide27PACE COUNT
Determining your pace count
Specifics for a pace course100 meters (Typically)
Varying terrainWalk in same gear you will have during land navigation exercise
27
Slide28CALCULATING PACE COUNT
Note your pace count.
Determine distance between the two points.
Use formula to calculate your pace count for the determined distance.
28
Slide29PACE COUNT FORMULA
P/100 = x/y, so:
Py
/100=xP = Your Pace County=Measured Distancex=Paces for that Distance
29
Slide30PACE COUNT FORMULA
Example:
Your pace count is 64. P=64
30
The distance is 500 meters.
y
=500
Py
/100=x
(64*500)/100=x
(32000)/100=x
320=x
It will take you 320 paces to walk this distance.
