Who performs field-level maintenance on or near the unserviceable piece of equipment or weapon system utilizing line replaceable units or modules and component replacement or repair?

• A. Maintenance officer
• B. Field Maintenance company
• C. Logistics squad
• D. Engineering company

Answer: (B)

At field level, maintenance is done close to where the equipment is used, with the ability to quickly restore capability by swapping out line replaceable units or modules and performing component repairs on-site. The Field Maintenance company is the unit specialized for this role, equipped and trained to diagnose, replace LRUs, and carry out necessary repairs so the equipment can be returned to service rapidly. This keeps operating units ready without waiting for higher-level repair facilities.

Maintenance officers provide oversight and coordination, but they don’t typically perform the hands-on, field-level repairs. Logistics squads focus on supply and parts movement rather than performing repairs. Engineering companies handle more technical or construction-focused tasks and higher-level repairs, not the routine field repairs using LRUs.
