What are the primary components of the Marine Corps divisions?

The primary components of the Marine Corps divisions include Infantry Regiments, Artillery Regiments, and Recon Battalions.

Infantry Regiments form the backbone of the Marine Corps and are essential for ground combat operations, designed to engage and close with the enemy. Artillery Regiments provide the necessary fire support to the infantry, delivering powerful, long-range artillery fire to neutralize enemy positions and support offensive operations effectively. Recon Battalions are crucial for gathering intelligence, conducting surveillance, and undertaking direct action missions, providing the division with vital information about enemy forces and terrain.

The other options outline different combinations of units that do not align with the core structure of Marine Corps divisions. The presence of specialized units such as Armor Regiments or unique support components like Medical Support Units and Logistics Companies, while important to overall Marine operations, do not represent the fundamental composition of a Marine Corps division.
