Hospital Shooting
When Gary Clark opened fire in Seattle Grace Mercy West Hospital, Marty and his team were called to neutralize the situation. ("Sanctuary")

He deployed teams into the hospital to clear them. One of the members of the SWAT team was able to shoot Gary Clark, but not catch him. They continued to clear the hospital one floor at a time, evacuating patients as they went. Once the shooter was identified, Marty asked Webber about him, which prompted Webber to go into the hospital to try to find him. After Webber got Clark to shot himself and end the massacre, Marty shook his hand. ("Death and All His Friends")
