Try rock climbing/mountaineering. Being in the wall few hundred meters above the ground, your mind doesn't care if there is securing rope tying you to last quickdraw or not. You will be scared. You will be bathing in adrenaline. You will have to muster all your courage to move forward, to climb higher, to reach the top. Again and again. You'll get all the excitement army guys get in deployment, without screwing you up and becoming permanent mental cripple. In fact, it will make you a better person in many many ways. Guaranteed.
