To keep from getting lost, a survivor must know how to find out where he is. A combat area has no street addresses, but a military map can help you identify a location accurately. The map has vertical lines (top to bottom) and horizontal lines (left to right). These lines form small squares 1,000 meters on each side called grid squares.

2. The lines that form grid squares are numbered along the outside edge of the map picture. No two grid squares have the same number.

3. The precision of a point location is shown by the number of digits in the coordinates: the more digits, the more precise the location.

1996- a 1,000-meter grid square.

192961- to the nearest 100 meters.

19269614- to the nearest 10 meters.

1. Look at Figure1. Your address is grid square 1181. How do you know this? Start from the left and read right until you come to 11, the first half of your address. Then read up to 81, the other half. Your address is somewhere in grid square 1181 (A, Figure 1.)

2. Grid square 1181 gives your general neighborhood, but there is a lot of ground inside that grid square. To make your address more accurate, just add another number to the first half and another number to the second half-so your address has six numbers instead of four.

a. To get those extra numbers, pretend that each grid square has ten lines inside it running north and south, and another 10 running east and west. This makes 100 smaller squares. You can estimate where these imaginary lines are.

b. Suppose you are halfway between grid line 11 and grid line 12. Then the next number is 5 and the first half of your address is 115. Now suppose you are also 3/10 of the way between grid line 81 and grid line 82. Then the second half of your address is 813. (If you were exactly on line 81, the second part would be 810). Your address is 115813 (B, Figure 1).

Bascially a repost of my crash course in GPS reading. But I support it...

And Pugs, I assume you're the same guy from Happy Time Platoon (TWC)?

There is only one "I WUB PUGS" on the World Wide Web. :D

So vanilla only gives us a 6 digit grid on the GPS? Man, ACE has spoiled me.

I'm bit confused here, when reading that shouldn't the Latitude (in this case 81) come before Longitude (11)? Or is this JUST for exact coordinates?
