A corps is typically composed of how many divisions?

• A. 9-12
• B. 2-5
• C. 1
• D. 6-8

Answer: (B)

A corps is a mid-sized army formation built to command and sustain several divisions under one headquarters. It is designed to be larger than a single division, providing enough manpower, firepower, and staff support to conduct independent operations, yet not so large that it becomes an army. This balance—more than one division but not an army-scale force—is what typical doctrine uses to define a corps.

So, the correct thinking is that a corps brings together multiple divisions under a unified command to achieve greater operational capability than a division alone, without stepping into army-sized complexity. A single division is simply a division, not a corps; a corps composed of a very large number of divisions would be closer to an army; and a size described as only modestly larger than a division would generally still be too small to qualify as a corps.
