(Please) Correct me if I'm wrong....
From what I understand, the US shooting teams are fielded by members of the military. They are picked out of the pack, and focus exclusively on their particular sport. They don't participate in wars, but instead train for and are sent to competitions like the Olympics.
With all that time, training, and the benefit of picking the elite out of thousands upon thousands, I don't like your chances.
Not to be a downer... and I could be wrong...
