- FM 3-25.26
- WHAT IS A MAP?
- A MAP IS GRAPHIC REPRESENTATION OF A PORTION OF THE EARTH'S SURFACE DRAWN TO SCALE , AS SEEN FROM ABOVE
- MILITARY MAPS ARE CATEGORIZED BY WHAT TWO THINGS?
- SCALE AND TYPE
- WHAT IS MEANT BY THE "SCALE" OF A MAP?
- THE SCALE IS EXPRESSED AS A FRACTION AND GIVES THE RATIO OF MAP DISTANCE TO GROUND DISTANCE
- WHAT ARE THE THREE DIFFERENT SCALES OF MILITARY MAPS?
-
SMALL SCALE 1:1,000,000 AND SMALLER
MEDIUM SCALE 1:75,000 TO 1:1,000,000
LARGE SCALE 1:75,000 AND LARGER - WHAT IS THE STANDARD "SMALL SCALE" MAP AND WHAT IS IT USED FOR?
- 1:1,000,000; IT IS USED TFOR GENERAL PLANNING AND FOR STRATEGICAL STUDIES
- WHAT IS THE STANDARD "MEDIUM SCALE" MAP AND WHAT IS IT USED FOR?
- 1:250,000; IT IS USED FOR PLANNING OPERATIONS, INCLUDING THE MOVEMENT AND CONCENTRATION OF TROOPS AND SUPPLIES
- WHAT IS THE STANDARD "LARGE SCALE" MAP AND WHAT IS IT USED FOR?
- 1:50,000; IT IS USED TO MEET THE TACTICAL, ADMINISTRATIVE, AND LOGISTICAL NEEDS OF FIELD UNITS.
- WHAT ARE SOME EXAMPLES OF DIFFERENT TYPES OF MAPS?
- TOPOGRAPHICAL, PLANIMETRIC, PHOTOMAP, JOINT OPERATIONS GRAPHICS (JOG), PHOTOMOSAIC, TERRAIN MODEL, MILITARY CITY, AND SPECIAL
- WHERE DOES A MAP GET ITS NAME?
- A MAP IS NAMED AFTER THE MOST PROMINENT CULTURAL OR GEOGRAPHICAL FEATURE.
- IDENTIFY THE COLORS USED TO FACILITATE THE IDENTIFICATION OF FEATURES ON A MILITARY MAP?
-
BLACK- MAN MADE FEATURES, ROADS, BUILDINGS
RED-BROWN THE COLORS RED AND BROWN ARE COMBINED TO IDENTIFY CULTURAL FEATURES FOR RED LIGHT
BLUE- WATER FEATURES
GREEN- VEGETATION
BROWN- IDENTIFIES ALL RELIEF FEATURES AND ELEVATIONS
RED- CLASSIFIES CULTURAL FEATURES - WHAT IS MEANT BY THE "MILITARYGRID REFERENCE SYSTEM"?
- A NETWORK OF SQUARES FORMED BY NORTH-SOUTH, EAST-WEST LINES SUPERIMPOSED ON A GEOGRAPHIC PROJECTION.
- WHAT IS THE DISTANCE BETWEEN GRID LINES ON A STANDARD LARGE-SCALE MILITARY MAP?
- 1,000 METERS
- WHAT IS THE MILITARY PRINCIPLE FOR READING MAPS?
- READ RIGHT AND UP
- HOW MANY DIGITS ARE REQUIRED TO LOCATE A POINT TO WITHIN 100 METERS? TO WITHIN 10 METERS?
- 6 AND 8
- THE GRAPHIC SCALE IS DIVIDED INTO TWO PARTS. WHAT ARE THEY?
- PRIMARY SCALE AND EXTENSION SCALE
- WHAT IS AN "AZIMUTH"?
- A HORIZONTAL ANGLE MEASURED CLOCKWISE FROM A NORTH BASE LINE.
- NAME THREE COMMON UNITS OF ANGULAR MEASURE USED BY MILITARY PERSONNEL TO EXPRESS DIRECTION.
- DEGREE 360; MIL 6400; GRAD 400
- DESCRIBE THE THREE NORTHS ON A MILITARY MAP.
- TRUE NORTH, MAGNETIC NORTH, GRID NORTH
- WHAT IS A "BACK AZIMUTH"?
- A BACK AZIMUTH IS THE OPPOSITE DIRECTION OF AN AZIMUTH
- WHAT IS THE BACK AZIMUTH OF 20 DEGREES?
- 200
- WHAT IS THE "DECLINATION DIAGRAM"AND WHERE IS IT LOCATED?
- IT IS LOCATED IN THE LOWER CENTRAL PORTION OF THE MARGIN AND SHOWS THE ANGULAR RELATIONSHIP BETWEEN TRUE NORTH, GRID NORTH, AND MAGNETIC NORTH
- WHAT IS THE GRID-MAGNETIC (G-M) ANGLE USED FOR AND WHERE IS IT FOUND?
- IT IS USED FOR CONVERTING FROM GRID NORTH TO MAGNETIC NORTH AND VICE-VERSA; IT IS FOUND IN THE DECLINATION DIAGRAM
- WHAT IS MEANT BY "INTERSECTION"?
- INTERSECTION IS THE LOCATION OF AN UNKOWN POINT BY SUCCESSIVELY OCCUPYING AT LEAST TWO KNOWN POSITIONS ON THE GROUND AND THEN MAP SIGHTING ON THE UNKOWN LOCATIONS.
- WHAT IS MEANT BY "RESECTION"?
- A RESECION IS THE METHOD OF LOCATING ONE'S POSITION ON A MAP BY DETERMINING AND GRID AZIMUTH TO AT LEAST TWO WELL-DEFINED LOCATIONS THAT CAN BE PINPOINTED ON THE MAP.
- WHAT ARE THE FOURTYPES OF COMPASSES DESCRIBED IN FM 3-25.26?
- LENSATIC, ARTILLERY, WRIST/POCKET, AND PROTRACTOR.
- WHAT ARE THE THREE MAJOR PARTS OF THE LENSATIC COMPASS?
- COVER, BASE, AND LENS
- THERE ARE TWO SCALES ON A LENSATIC COMPASS; THE OUTER SCALE, NORMAILLY IN _____ COLOR DENOTES ______ AND THE INNER SCALE, NORMALLY IN _______ COLOR DENOTES ____________.
- BLACK, MILS; RED, DEGREES

- WHAT ARE THE FIVE METHODS OF DEPICTING A RELIEF?
- LAYER TINTING, FORM LINES, SHADED RELIEF, HACHURES, AND CONTOUR LINES.
- WHICH RELIEF METHOD IS THE MOST COMMON ON STANDARD TOPOGRAPHIC MAPS?
- CONTOUR LINES
- WHAT ARE "CONTOUR LINES"?
- IMAGINARY LINES ON THE GROUND THAT CONNECT POINTS OF EQUAL ELEVATION
- WHAT ARE THE THREE TYPES OF CONTOUR LINES?
- INDEX, INTERMEDIATE, AND SUPPLEMENTARY
- WHAT ARE THE FIVE MAJOR TERRAIN FEATURES?
