Define trail of a convoy.

• A. The front vehicle that leads
• B. The main escort vehicles
• C. The trail is the fuel cell and medical units
• D. Fuel vehicle, ambulance, bobtail, wrecker, trail officer checks and observes vehicles at SP, updates CC on vehicles that fall out and oversees maintenance

Answer: (D)

The trail of a convoy is the rear section that follows the main body to support and monitor the move. Its job is to keep the convoy running smoothly by tracking all vehicles, providing essential support, and handling any problems that arise after movement. This includes the tail vehicles like the fuel truck, ambulance, bobtail, and wrecker, plus a trail officer who checks and observes vehicles at stopping points, reports any that fall out to command, and oversees maintenance. This holistic rear-guard role—ensuring accountability, logistics support, and vehicle readiness—is what defines the trail.

The other options describe roles at the front or focus on only specific components, not the comprehensive rear support function.
