You're flying an A-10, tasked with the elimination of some high-priority targets in Afghanistan. Upon reaching the village, you see that it's full of women and children who would surely be wounded or killed by your fire. Do you press the attack and accomplish the mission, or do you keep your finger off the trigger in hopes of saving innocent lives?

You're already in the military and are sitting in front of two retired Colonels who you've just met. Each must be around 75 years old (but for the purpose of the scenario, they're both still active duty). One turns to you and tells you that you're now under his direct command. In a minute, he'll give you a pistol, and he orders you to shoot the other. Do you follow his order?

These are the two that stand out in my mind - the two for which I didn't have a solid, immediate answer. Practice moral/ethical questions like this, because they can be the toughest ones by far.
