The quote from Iain M. Banks' "Use of Weapons" reflects a soldier's adherence to duty and a pragmatic approach to military life. The good soldier follows orders without question, suggesting a level of obedience that is often expected in military settings. This perspective implies that while soldiers are trained to execute their commands, the notion of voluntarily seeking higher rank or responsibility can be seen as unnecessary and even unwise.

Moreover, the quote suggests a critical view of ambition and promotion within the military hierarchy. By advising against volunteering for promotions, it highlights the potential risks and challenges that come with higher positions. This approach indicates a preference for stability and safety over the uncertainties and pressures that accompany leadership roles, shedding light on the internal conflicts faced by individuals in such systems.
