The choice of food parallels some modern-day vegan athletes who thrive on plant-based nutrition.

This harsh method served as a deterrent to insubordination, ensuring compliance through fear. Despite its severity, decimation was not frequently employed, as it risked lowering morale. However, the mere threat of such punishment reinforced the importance of unity and obedience among the troops.
