Lawrence Kimbala, codenamed "SHONA", was a member for the Spec OpsEcho Six unit, and operated as the team's field scientist. He was often seen in quiet reflection with a solemn look on his face, most likely due to the enormous amount of death and suffering that he has witnessed thus far.
Lawrence was an African of Shona descent,[notes 1] who grew up in southern African nation of Zimbabwe, where he helped treat diseases. In Zimbabwe, he studied a number of viruses and diseases such as Ebola; HIV; typhus; cholera and staphylococcal infections with his father, who was a biologist.
After his father's death, Lawrence attended the Harvard medical school, where he studied virology and discovered he had a skill for controlling viruses instead of curing them. With this knowledge, he was selected for the Army's special weapons program as a military doctor.
