Wartime Infantry Division (triangular)
 
Symbols Glossary
 
This depicts a typical organization for a wartime infantry division found in China. As can also be seen from the diagram above, actual organizations and equipment could vary from division by division. On paper, the triangular (three infantry regiment) Infantry Division had about 14,100 men. But the divisions were seldom as neat and tidy as this diagram. Elements were consistently being attached or detached, so that some divisions had as few as 10,000 men and some as others as many as 20,000.

The units in the divisions did not not always have the same size or configuration. A typical example would be the reconnaissance "regiment". In some divisions this was a cavalry-motorized unit, in others it was a battalion sized unit of horse cavalry, and in some divisions a reconnaissance element was missing altogether.

The artillery suffered similar variations being equipped with different types and numbers of guns, etc.
