Which of the following supports field maintenance in combat operations?

The Field Maintenance Company is specifically designed to provide maintenance and repair support in combat operations. It focuses on sustaining equipment readiness by performing repairs on various types of vehicles and equipment directly on the battlefield or in close proximity to combat operations. This integration into the operational environment allows for rapid response to equipment failures, which is crucial for maintaining combat effectiveness and operational tempo.

In the context of large-scale combat operations, the Field Maintenance Company plays a vital role in ensuring that units can remain operational despite the challenges of combat, including wear and tear on equipment. This capability enhances the overall effectiveness of ground forces by minimizing downtime due to mechanical issues.

While other options may also provide support in a broader logistical context, none of them have the specific focus on field-level maintenance that is critical during combat operations.
