What types of units provide fire support to the GCE?

The correct option focuses on units specifically designed to deliver fire support to the Ground Combat Element (GCE). Guided Missile Units, Field Artillery Units, and Naval Gunfire Support Teams are specialized forces that provide artillery and naval support, essential for engaging enemy forces and supporting maneuver elements on the battlefield.

Guided Missile Units use precision-guided munitions to strike targets at extended ranges, significantly enhancing the GCE's capabilities against heavy enemy fortifications or armored units. Field Artillery Units provide indirect fire support through various artillery systems, which are crucial for bombarding enemy positions and providing combined arms support. Naval Gunfire Support Teams coordinate naval ship bombardment, allowing the GCE to leverage naval assets for effective fire support during amphibious operations or ground engagements.

This comprehensive approach ensures that the GCE is supported by various firepower options tailored to the specific operational context, making it more effective in accomplishing its missions while protecting its forces.
