Who is Specialist John Stebbins from Black Hawk Down: A Story of Modern War and what is their importance?

Specialist John Stebbins joined the Rangers to see fighting, but when commanders learned he could type they assigned him to be company clerk. Stebbins watched as all his fellow soldiers went on mission after mission only to be left behind. On October 3, due to the fact that fellow Ranger Specialist Sizemore would not be able to fight because of an infection in his elbow, was assigned to join the mission in Mogadishu.
