Captain Kudo's response to his experience with the men on the motorcycles in Afghanistan is <em>D. He quickly accepted what happened and moved on because doing so helped save his troops lives.</em>
Though it was a war situation, where the enemy could be the next civilian, whenever a civilian is killed by mistake, it is always regrettable. The experience leaves a trauma in the minds of the soldiers.
Sometimes, such ugly outcomes cannot be eliminated. However, soldiers should always seek more <em>information</em> about the status of military targets.
Captain Kudo'sresponse is not to feel guilt over the two civilians killed or regret not taking action to protect his men. Captain Kudo's reaction is not that he does not think about killing civilians in Afghanistan. He thinks about this and does not want to do that because it is not justified.
Thus, Captain Kudo's response was to accept the incident to safeguard and not demoralize his troops.
