I stood up and led the exercise : UBC Broad Based Admission Questions for Commerce.

Describe your most significant leadership experience. Why do you consider this your most significant role? (maximum 200 words)

The summer of 2010, a group of friends and I participated in a two days military training in China. The training was organized by a friend's dad. On the first day, we had some intensive exercise. We then proceeded to learn how to carry a rifle. The soldier taught us how to go from a sling carry to a patrol ready position. I was a fast learner and mastered it after a short while. The next day we did the same activity, however, it was not the same experience as day one. I stood up and led the exercise -sit ups, push-ups, jumping jacks and runs. While we were running in a circle, one of the younger participants was exhausted very quickly. I encouraged him and ran by his side. Later when we were doing the gun shifting exercise, the same boy had trouble doing it. Thus, I approached him and step by step demonstrated the proper way of changing the position swiftly and smoothly. This leadership experience had an impact to me since I could relate it to war. Imagine soldiers had no leader in a war; they would just be digging themselves a hole. A leader is not just someone that gives out order, but the one that people can seek for assist from.

This is not adding any value to your answer. This one you can leave out : )

I think you should come up with a stronger claims to show that you have shown true leadership qualities there. Tell them what happened to that boy and what were his problems. Then what strategy you applied to motivate him and lead him towards success... This should be a more convincing account. :)
