Which resupply technique allows units to move to a designated site for resupply or equipment turn-in when contact is not likely?

The Service Station Technique is designed specifically for scenarios where units can relocate to a predetermined resupply location when the chance of enemy contact is minimal. This technique focuses on efficiency and security, allowing units to gather at a safe and designated site to receive supplies or turn in equipment, which helps streamline the resupply process.

In contrast, the other resupply methods are typically employed in different operational contexts. The Modified Tailgate Technique and Tailgate Technique are more suitable for situations where units need to remain mobile or are actively engaged in operations, as they emphasize immediate resupply without moving to a designated site. The Direct Resupply Technique, while efficient in terms of delivering supplies directly to units in the field, may not address the scope of a strategic and secure resupply as effectively as the Service Station Technique does when contact is not expected.

Thus, the Service Station Technique is specifically tailored for situations where units can afford to regroup and conduct resupply without the ongoing risk of contact, making it the most appropriate choice.
