Munley's grandmother Monirie Metz told ABC News that the former South Carolina surfer girl would probably object to being called a hero.
"Kim doesn't want be called a hero. She's worried about everyone else right now and is very concerned about her colleagues with whom she is very close," Monirie said.
With the majority of the Army's military police attachments deployed to Iraq or Afghanistan, civilian police officers have been hired in large numbers to provide security for the bases stateside. They are contracted, Banks said, from private companies.
"Their role is just the same as the military police officers. They do everything that they do," he said. "Hey, they are great. They do an excellent, excellent job."
In the hours after the shootings, two Facebook groups sprung up dedicated to Munley and her heroic actions.
"At that tragic moment you were able to use your training and abilities to bring an end to a day that will haunt the lives of many for years to come," one member posted in the group "God Bless SGT Kimberly Munley." "Thank you for being a true hero."
And in the group "Sgt. Kimberly Munley: A Real American Hero!" one woman stationed in Japan with her military husband said that Munley had inspired her to learn how to shoot once she returned to the U.S.
