 The scenario Ullmann-Margalit presents is an example of a  prisoner’s dilemma  and is illustrated in  Figure 1  below. In this strategic form game, each soldier acts without observing the other’s action. Each soldier has the choice between the strategies of fleeing (F) or staying (S). The cells in the matrix correspond to the outcome of each possible pair of choices, with the numbers in the cells representing the utilities of the outcomes for the soldiers. Specifically, higher numbers correspond to a more preferred outcome, and the first number represents the payoff of Soldier 1 who chooses between the actions corresponding to the rows, while the second number represents the payoff of Soldier 2 who chooses between the actions corresponding to the columns.
