Beat Shooting Range Quickly
Select the laptop gun from the weapons in the firing range and put it on bronze. Hold B, turn around, and pull the trigger. Immediately press Start, before Joanna can throw the gun, and abort. Then quickly press Start again and select any other weapon from the menu. As soon as the new target range starts, the sentry gun will be thrown out and stuck to the wall. This trick is cheap but can get you most of the medals.
