I added a fictional battalion to the United States Marine Corps when I built the world for Rough Passages.Here's the thing about military units: they have insignia. That reality gave me a great excuse to look at unit badges and design one for the valiant second-career rollover Marines in Mercury Battalion.I also built a Table of Organization for the Battalion, named all the companies and planted them all over the United States in proximity to the bases that support them, but that's trivia for another post.Here's my take on Mercury Battalion's Unit Badge. I swear I posted about this before now, but all I could find was a Facebook post. And those don't count. So, Here:For those interested in details:Mercury Battalion was formed out of the 4th Marine Division in 1944, a few months after the 4th Division was pulled into emergency service after First Night.Initially tasked only with protection of the civilian population, the 4th Division's mission objective quickly expanded to include drafting and training hazardous rollover civilians as Marines themselves--in part as as an alternative to mass permanent incarcerations, and in part because the adage "fight fire with fire" had literal and practical application.Over time Mercury Battalion has become the default post-rollover duty assignment for citizens whose powers are too deadly, too destructive, or too sensitive to be handled by the Department of Public Safety.And why bother with an origin story I don't intend to expand? Because being me, I had to come know which Division's colors and symbols would best suit my creation.I'm picky that way. I used units in both the 4th and 5th division as my main inspirations. If anyone is wondering.
