Leo Braudy is the Bing Professor of English and University Professor at the University of Southern California.

Braudy stresses the historical and cultural components of masculinity in relation to war and notes how these change over the centuries in relation to such factors as the social structure of society, the nature of political power, the available modes of technology, and the idea of the state.

He argues that an important shift in the relationship of war and gender in the nineteenth and twentieth centuries is a retribalizing of the entire male community and a return to the warrior sensibility and the gender polarization on which it depends. Today military personnel are citizens of a nation rather than subjects of a ruler and are recruited and inspired by the idea of the nation or the state to which they owe a sacred allegiance. In turn, national identities emerge out of myths, traditions, and beliefs. They are also created by identifying what the nation is explicitly not - for instance, highlighting differences of race, gender, ethnicity, or cultural norms that readily transforms into an "us versus them" view so useful in warfare.

In the twenty-first century, Braudy notes that these easy polarities are breaking down and asks, "Does the female or the homosexual soldier undermine the traditional military need to see the enemy as feminine? It is a question that has preoccupied democratic armies in the past in the shape of the Jew, the African American, or any other group that had previously been seen as marginal or subordinate to the so-called real men of mainstream society."

Braudy concludes that all polarities can be remapped as masculine/feminine, especially the "us versus them" of warfare. When such polarities collide, they may cause entrenched aspects of the old war gender system to break down.
