It's from a prestige power called Team Transport - if you activate it, you click on the Longbow Chaser (or an Arachnos Flyer if you're a villain/rogue) and it teleports you to the door of your active mission. Since it's designed to work for teams of players, the model lingers for a bit after it's summoned so everyone on your team has time to click on it. As for getting it, you can buy it from the P2W Field Agent for 10 million Influence (Prestige Powers -> Travel -> All the way at the bottom of the list).

Oh no, yeah, that's completely understandable - especially now given how active the Brickstown event is and how absolutely dead the Redside tutorial is (plus the 10+ years since the badge was first put in the game <.<;). I've had multiple global friends say the exact same thing, and I barely recognized it myself at first. 'Salright! ^_^

I don't think it's a bug - that badge was originally pushed to live in November 2006 to celebrate CoV's launch on Halloween in 2005 (Paragonwiki Link). So the devs probably just put it out there this month as another way to get an otherwise unobtainable badge.
