In this chapter, I state and briefly explain the military canon of conduct that constitutes its honor code. I then document some prominent cases of military honor and dishonor. Finally, I explain under what circumstances the military honor code is most likely to resonate and support military rectitude and under what circumstances the military honor code is most likely to fail. Pivotal to this understanding will be conflicts between (a) loyalty to peers and to unit, and the internalized imperative to preserve their reputations, and (b) the principle of holding dishonorable peers and dishonorable conduct to account.
