The 33rd did what they could. Konrad wanted to save people by evacuating them, but they just could not, so as all hell was breaking loose in Dubai, fighting over resources, he instored the martial law. For instance, he protected the water so everyone could have a ration, even if it meant killing people. Some members of the 33rd revolted out of a sense of despair, and he had to make examples and kill them too. He committed suicide eventually. Throughout the game, Walker makes sense of it all in great difficulty, and we realize that Konrad had been dead all along. The radioman had Konrad's voice in his broadcast because the broadcast echoed on the storm walls. When we hear Konrad through the walkietalkie, it's different, it's an hallucination: Walker understanding what happened, although it materializes in denial. Nobody in the story had malicious intent, they just had different interpretations on what had to be done, and even of what was happening. For instance, Briggs argues that if nearby countries heard of a US battallion instoring martial law in Dubai, it would cause a world war that the US could not afford, and thus, everyone had to die in Dubai. This is crazy, this is cold, but this is an argument. Nobody is right, everyone suffers, this is war, where there is no hero.
