In the novel, the soldiers carry guns of many different sizes—the biggest of these, the “big rifle,” is a large, powerful firearm, usually entrusted to one of the most experienced soldiers. For much of the novel, Harold Murphy carries this weapon, while at other times, Oscar Johnson does. By the end of the novel, however, Paul Berlin is the one who must use the rifle to kill Cacciato, whom he’s tracked down to a hotel in Paris. The fact that Berlin now carries the big rifle suggests that he’s matured as a man and a soldier, but the fact that Berlin is unable to use the rifle successfully (he fires blindly, and it’s not clear if he hits anything), suggests that Berlin is still young, and in many ways inexperienced.
