Which division uniquely has regiments with four battalions?

• A. 2nd Marine Division
• B. 1st Marine Division
• C. 3rd Marine Division
• D. 4th Marine Division

Answer: (B)

Infantry regiments are built from battalions, and the number of battalions assigned to a regiment affects how many infantry units sit under that regiment without adding more regiments to the division. The 1st Marine Division is the one among those options that uses regiments with four battalions each, rather than the more common three battalions per regiment seen in the others. That four-battalion regiment structure makes it unique to this division, which is why it’s identified as the division whose regiments have four battalions.
