Admin How do you plot a grid azimuth?
Using the edge of your protractor, draw a straight pencil line between points A and B. The line is your azimuth. Now you must determine the grid azimuth of that line—the angle between the line and grid north. The terms azimuth and direction are interchangeable.
How many scales are on a military protractor?
Around the edge of the protractor there are three scales; the outer is marked in mils, the centre is marked in degrees and the inner is marked in black azimuths.
What is the general rule for reading military grid coordinates?
When reading a military map, use the number along the left border of each grid square as your starting point; then read the number along the bottom border. The general rule of military map reading is “right and up,” which means you read a military map to the right of each left border and upward from each bottom border.
What is grid azimuth used for?
When an azimuth is plotted on a map between point A (starting point) and point B (ending point), the points are joined together by a straight line. A protractor is used to measure the angle between grid north and the drawn line, and this measured azimuth is the grid azimuth (Figure 6-4).
How do you plot a military grid?
Look at the top of your map at the easting numbers, and move right until you find the 30 grid line. Look at the side of your map at the northing number and move up until you find the 95 grid line. Follow the lines to where they intersect. That is the bottom left corner of the grid square that we’ll be working with.
How to find the azimuth line in a protractor?
mark on the protractor and read to the right (clockwise) until you reach the point where the azimuth line crosses the scale (s) of the protractor.
Which is the correct direction for a military protractor?
Military protractor. b. When using the protractor, the base line is always oriented parallel to a north-south grid line. The 0- or 360-degree mark is always toward the top or north on the map and the 90° mark is to the right.
How do you make a protractor on a map?
1. Place your protractor on the map with the index mark at the center of the known point and the base line parallel to a vertical, north-south grid line. 2. Using your pencil, make a small tick mark on the map at the edge of the protractor at the desired azimuth.
Which is the military protractor GTA 5-2-12?
The military protractor, GTA 5-2-12, contains two scales: one in degrees (inner scale) and one in mils (outer scale). This protractor represents the azimuth circle. The degree scale is graduated from 0 to 360 degrees; each tick mark on the degree scale represents one degree.
