What about the actions of these men exemplifies them as hemingway heroes?
they talk about the oncoming attack, clearly with a deep sense of worry for their own safety and the salety of others
they have not yet lived through a battle and are naive about the imminent danger that awaits them.
they have the bond only men in battle can share, and this is related by the way they partake of the cigarettes
they act casually and go about regular business, such as smoking, while actually in grave danger.
