What should soldiers avoid doing during the measurement to ensure accuracy?

• A. Do not tense muscles, hold breath, wear bulky clothing, or otherwise interfere with the measurement.
• B. Engage in heavy exercise immediately before.
• C. Skip meals before measurement.
• D. Take measurements while running.

Answer: (C)

Accurate measurements come from the body being in a steady, non-fluctuating state. Temporary changes from recent intake, hydration, or activity can alter the readings and make them less reliable. Skipping meals before the measurement would introduce such instability by changing digestion and fluid balance, which can shift the numbers you’re trying to capture. For that reason, not skipping meals prior to the measurement helps keep results consistent. In contrast, actions during the measurement like tensing muscles, holding breath, wearing bulky clothing, exercising heavily beforehand, or taking measurements while moving would all interfere with the process and distort the results, so those should be avoided to ensure accuracy.
