Background Information
Unfortunately, since Starfleet personnel in both the security and engineering departments wore the same color uniforms on all the television series (except the Star Trek films), it can sometimes be difficult distinguishing which department said personnel belong to. This list is only for personnel that were definitely seen as a component of an engineering detail or mentioned as being assigned to engineering. There are probably many more Starfleet operations division personnel that might either be security or engineers.
