Which statement about WWI square divisions is accurate?

• A. It was created during WWI to achieve mass, depth, and staying power
• B. It consisted of three regiments and was highly maneuverable
• C. It was significantly smaller than triangle divisions
• D. It was primarily used in rapid open-field maneuver

Answer: (A)

In WWI, square divisions were four-regiment infantry formations organized as two brigades, each with two regiments. This arrangement gave a division more infantry in a single front, creating mass to hold a sector and depth to absorb artillery strikes, which directly translates to holding power or staying power in the static, attritional fighting of trench warfare. The idea was to project enough force to man a length of line and to sustain operations under bombardment, rather than to enable rapid maneuver.

That’s why this statement is the best fit: it captures the purpose of square divisions—providing mass, depth, and resilience in the face of a grueling, protracted front. The other statements don’t fit the historical role: three regiments describe a triangular division, which came into prominence later for greater flexibility; being smaller than triangular divisions is incorrect; and rapid open-field maneuver was not characteristic of WWI’s trench warfare, where fixed fronts and attritional tactics dominated.
