People who own starfleet uniforms rarely purchase the low status ones. I'm at a trekkie event, and all I see is command staff. No ensigns, so science crew... this is either statistically inaccurate OR only command staff have the free time to go to trekkie events.
NPR was talking about Naval budget cuts, and the number of 'literal combat' ships in the fleet. Which I thought was odd, until I realized they were discussing 'littoral combat' ships. Then I had coffee.
