Terminology

Under the hood ORBAT Mapper uses a data model loosely inspired by the Military Scenario Definition Language (MSDL). In this section we will go through some terminology you will encounter while building a scenario.

Sides and groups

A scenario consists of units organized into groups and sides. A side typically represents a nation or coalition. In a WWII scenario the sides would typically be Allied forces and Axis forces.

For each side you can specify a standard identity / affiliation. The standard identity determines the color and shape of the unit icons. The most commonly used ones are friend, neutral and hostile:

Friend

Neutral

Hostile

You can also select custom colors. This is useful in cases when you do not want to label a side as hostile or want to distinguish different nations by symbol color.

Each side consists of one or more groups of units. A group is just a way to organize your units. They can for instance represent branches (army, navy, air-force, etc.), a task force, a battlefront, etc. The default group name is Units.

A group consists of one or more unit hierarchies. The topmost unit in a hierarchy is called a root unit.

Units

A unit is the basic building block of a scenario. It has properties like military symbol, name, description, echelon, location, etc.

Table of Organization and Equipment (TO&E)

A military unit is composed of personnel and equipment. This composition is often referred to as Table of Organization and Equipment (TO&E). The TO&E outlines the structure, roles, and responsibilities of personnel within the unit and specifies the types and quantities of its equipment.

ORBAT mapper has basic support for representing TO&E-data.

Map layers and features

The map is an important part of a scenario. A scenario map consists of multiple layers. The base layer is drawn first an on top of that you can add raster map layers and then feature layers.

A raster map layer consists of one or more raster images. Typical raster map sources are aerial photos and scanned maps. Feature layers consists of one or more features. A feature is a styled point, line or polygon on the map.
