[quote=@Blue Demon] Whoops. Overlooked this. My short answer... It's Star Trek. Wouldn't be unheard of. [sub](Screw Protocol right?)[/sub] Long answer... As long as it make sense why your character might be tagging along I'd probably allow it. But if they're there just for kicks and giggles? There's probably an issue. [/quote] During the Dominion War Starfleet Engineers were gold on the planetary battlefields; the right one could expose 'shrouded' Jem'Hadar, get you through force fields, or turn a tricorder into a life saving device on the fly. The Dominion forces, including their Cardassian and Breen counterparts, had no answer for Starfleet Engineers. Chief O'Brien from DS9 is a prime example of this. tl;dr - Protocol changed during the Dominion War.
