Which of the following is NOT a part of the straddle trench procedure?

The straddle trench procedure is a tactical method used by Marines for personal waste disposal in a field environment, ensuring sanitation and minimizing environmental impact. In this context, the correct answer highlights an action that is not typically included in the standard procedure.

The correct response—covering the trench with plastic—does not form part of the traditional straddle trench guidelines because this procedure focuses on digging and dimensions, while proper covering techniques involve using soil or other natural materials to secure the trench after use. The emphasis is on ensuring that the trench is properly constructed and maintained.

In contrast, other components of the straddle trench procedure involve specific measurements and construction techniques, such as the length, width, and depth of the trench. These physical characteristics are critical in creating a functional straddle trench that best serves its purpose while prioritizing the health and safety of personnel operating in the field.
