UED Science Corps

The UED Science Corps was the scientific wing of the United Earth Directorate. It was present in the battle Fury of the Swarm in StarCraft Episode VI, where its forces included the following special units: UED scientists, UED Genetic Engineers, UED Pyrotechnic Engineers, and UED security guards.

History
Shortly after Infested Kerrigan defeated the United Earth Directorate forces on Korhal and retreated to Tarsonis, the UED responded with a counterattack, sending a pair of Slave Broods to attack Kerrigan's forces.

UED scientists coordinated the zerg forces, working alongside genetic engineers which were conducting experiments on passive zerg. Security guards and pyrotechnic engineers were assigned to protect the scientists. However, Kerrigan's forces defeated them, defeating the Slave Broods and killing all the scientists. The formerly passive zerg then rampaged across the battlefield.

Given the subsequent destruction of the entire UED Expeditionary Fleet, it is likely that the UED Science Corps no longer exists, unless they are a larger organization and there are more of them back on Earth who never left, or else if some of them were not present in the battle on Tarsonis and somehow managed to survive as UED Remnants.
