I'm the Science Officer for the space station Deep Space Nine. The job requires combat skills, since sometimes we can be put into dangerous situations that require such skills.
Really? That's fascinating. The Enterprise currently has Starfleet's first ever android officer. His name is Data. I've never had the pleasure of meeting him, but I've heard he is quite interesting.
He doesn't have control over my bodily functions or where I choose to move, if that's what you're asking. I make the decisions as to where my body goes, although I do take into consideration what his desires may be.
