the shooting range is unlocked by completing the campaign. after you beat the last level, go back to the missions list, and scroll to the bottom. a new mission called Shooting Range will be there. basically, you spawn in a military shooting range, with a bunch of targets at various distances from you. you are equipped with every weapon, and ten of each grenade. You're also immortal.
