Which of the following best describes a mercenary's loyalty?

A mercenary's loyalty is best described as conditional on the payment received because they are primarily motivated by financial gain rather than allegiance to a particular nation or cause. Unlike soldiers who fight for national pride or a deeply held belief, mercenaries enter into contracts to serve whoever pays them, which means their loyalty can shift depending on who offers the best compensation. This understanding highlights the transactional nature of their service, distinguishing it from other forms of allegiance associated with national or ideological commitments. Consequently, a mercenary's loyalty is not unwavering; it varies with the conditions of payment and contracts, emphasizing the practical and self-interested motivations behind their actions.
