R. Richards took part in the combat exercise between the MACO's and several Earth Starfleet officers due to a conflict between Major Hayes and Lieutenant Reed. His opponent was Subcommander T'Pol, who knocked him several times to the ground. At one point, when T'Pol was put off guard by the behavior of Commander Tucker and Amanda Cole, Richard knocked T'Pol to the ground. (ENT: "Harbinger")
Corporal Richards was also part of the rescue team for Hoshi Sato and beamed on board the Xindi Insectoid ship. During the following shootout with the Xindi-Insectoids, MACO S. Money was wounded and Richards beamed alongside Money back to Enterprise. (ENT: "Countdown")
When Enterprise tried to destroy the Xindi superweapon, three Sphere Builders appeared on board the Earth Starfleet ship and damaged it heavily. Richards was part of the commando which tried to stop them but was not successful. (ENT: "Zero Hour")
The same year, Corporal Richards guarded the quarters of the Andorians Shran and Talas on board Enterprise. Talas tried to seduce him but when he resisted, she knocked him unconscious after both shared a hand-to-hand combat. (ENT: "Babel One")
