Which Marine Corps units fall under the GCE?

The Ground Combat Element (GCE) is a component of the Marine Corps that is primarily responsible for land-based combat operations. It encompasses units that are directly involved in ground combat. The correct choice appropriately lists infantry battalions, reconnaissance battalions, artillery regiments, and tank battalions, all of which are integral to the GCE.

Infantry battalions form the backbone of the Marine Corps' ground combat capabilities, providing the main ground force for seizing and holding terrain. Reconnaissance battalions support this mission by gathering intelligence and conducting surveillance, vital for informing operations. Artillery regiments provide fire support, delivering powerful indirect fires to assist ground forces. Tank battalions enhance the combat power of the GCE with armored vehicles, capable of engaging enemy forces and supporting infantry operations on the battlefield.

The other options contain units that serve different functional roles outside the direct ground combat responsibilities of the GCE. Logistics battalions and supply depots, for instance, are crucial for ensuring that combat units have the necessary supplies and support but are not themselves combat units. Similarly, cyber warfare units and communications companies focus on electronic warfare and communications, which are essential to overall operational effectiveness but do not engage directly in ground
