This paper presents in detail the organization of a type field army designed for combat in a mid-intensity conflict, Central Europe, in the 1970's. The methodology used to develop the force is unique to previous published attempts in that combat support and combat service support units were allocated on the basis of quantitative workloads generated by a war-game. The conclusion reached is that the field army developed by a rational process is much larger--by almost one-third--than that structured without considering the combat environment, intensity of combat, and the resultant workloads to be satisfied.
