The officer's ruler is a special device designed for the work of an officer. It is made, as a rule, of transparent plastic, looks like a rectangle with various slots. Depending on one or another type, patterns, stencils, a protractor, divisions for measuring distances or angles, for applying conventional signs, for example, on topographic maps, can be placed on it.
Scope of application
An officer's ruler is used, the photo of which you see above, mainly for orientation on a topographic map, to determine more accurate coordinates. In addition, you can easily measure angles, draw shapes, fonts and numbers with it.
Any officer's ruler is a universal working tool that combines a variety of drawing devices. It is mainly used for measurements (for example, on maps and plans), for convenient drawing on working documents of such conventional signs as restricted areas, flood or fire zones, areas of radiation, biological or chemical contamination, placement of various types of weapons and equipment.. Also rulerofficer allows you to mark on the maps roads, columns and special routes. In addition, with the help of it you can create any graphic images, plans and diagrams.
Description
Any officer's ruler includes (in addition to such a simple measuring geometric tool as a ruler) a scale scale, a protractor with a two-sided millimeter division scale and stencils. In addition, it necessarily contains special inscriptions and images, as well as a variety of geometric shapes. For example, it can be rectangles, circles, triangles, squares and ovals.
Main species
Currently, it is customary to distinguish between two main types of such a product - an officer's marine line and land. The first is designed to simplify and speed up the laying of the path of various ships. Such a tool easily replaces the commonly used protractor and parallel ruler. In addition, it allows officers to dispense with the necessary compass correction calculations. Thus, the possibility of calculation errors can be eliminated.
Finally, this simple calculator makes it possible to "remember" the deviation table, as well as the course followed by the ship, and the corresponding corrections on this course.
As for the land officer line, in addition to applying standard geometric shapes and symbols, it allows you to make designations such as a cannon(field gun, howitzer), machine gun (manual, easel), parachute (landing), communication station and observation post. The designations of all signs presented on this tool, which, depending on the additions inside and outside, can change their meaning, are described in detail in a special manual called “Commander’s Work Card”.
