Raiding party member (2154)
This MACO was part of the raiding party led by Captain Jonathan Archer in 2154, which boarded the Illyrian starship to rob technology and supplies. The team was attacked by the Illyrian soldiers but the mission became successful. This MACO was part of the last three officers who transported back to Enterprise. (ENT: "Damage")
This MACO was portrayed by stunt actor Zane Cassidy, who received no credit for his performance.
This MACO guarded the sickbay where Talas was treated after Naarg shot at her. He watched the last conversation between Talas and Shran, moments before she died in his arms. (ENT: "United")
When Captain Archer was under the influence of Xindi-Insectoids, he was working in a shuttle bay and shot unconscious by the senior staff who tried to retake Enterprise. Later he served at the science station on the bridge when the senior officers, including T'Pol and Malcolm Reed, invaded the bridge and was shot unconscious again. (ENT: "Hatchery")
This MACO was portrayed by stunt actor Justin Sundquist, who received no credit for his appearances.
Above are the only confirmed MACO casualties. There are numerous instances where a MACO is see shot in one episode and apparently dies only to be seen in the next episode alive. Also, the name tags seen on MACO uniforms seem to switch at random, making an accurate count of KIAs impossible.
Almost all of the MACOs were portrayed by stunt performers or actors with a stage combat background or experiences.
Due to the re-use of costumes and name tags, several performers portrayed one character, for example E. Hamboyan, who was played by at least three actors.
The complement of MACO on board Enterprise during the Xindicrisis is given as 36 in the novel Last Full Measure. Additional MACO named in this novel are Corporal Selma Guitierrez, Corporal McCammon, Corporal Meredith Peruzzi, and Private Colin Eby.
