He saw combat in numerous Earth military engagements, such as the Resource Wars, without injury. He survived three tours in Nigeria with the Marines' First Reconnaissance Battalion
However, on his first day on Pandora, he was attacked by viperwolf, ending his lucky streak and caused him to become fearful and resentful of the moon. This also gave him a trio of trademark scars to the right side of his head and face. He was given the option to return home to Earth for reconstructive surgery but opted to stay on Pandora. With his impressive record, he was eventually chosen as the chief of security operations on Pandora in 2152
Quaritch was the chief of security for at least two years He was responsible for the security of the RDA operation and its personnel, which necessitated keeping the Na'vi in check. He had his own Dragon Assault Ship, which was personalized with an orange-colored Chinese dragon painted below the cockpit. During this time Quaritch also included a relationship with one of his scorpion pilots named Paz Socorro which resulted with the birth of a son named Miles Socorro shortly before the Battle of Ayram Alusìng
