How is a Forward Support Company's capability in transporting Class III (B) described?

The capability of a Forward Support Company in transporting Class III (B) fuel is most accurately described through the Tank Rack Module. This modular system is specifically designed to facilitate the transport and distribution of bulk petroleum products, ensuring that fuel can be delivered efficiently to support combat operations. The Tank Rack Module is mounted on various vehicles, which allows the Forward Support Company to maintain mobility while providing critical logistical support.

The other options do not effectively convey the primary method used for transporting Class III (B) fuel. For example, MREs (Meals Ready-to-Eat) pertain to food supplies, Light Tactical Vehicles, while versatile, do not specifically relate to fuel transport in the same manner as the Tank Rack Module, and Heavy Equipment Transport Systems are geared more towards moving larger vehicles rather than transporting fuel. This reinforces why the Tank Rack Module stands out as the correct choice for describing the Forward Support Company's capability in fuel transportation.
