The New England Federation Starfleet is the most common way most people outside the Federation interact with the Federation. Their starships travel everywhere in Alliance space and beyond. Starfleet personnel are trained to be courteous, trained to be kind, trained to smile, and most importantly, trained to put a bullet in the favorite piece of anatomy belonging to anyone who threatens a Federation citizen, in Federation space or beyond. They will participate in search and rescue operations, help defend a world from raiders, or simply talk nicely as they spend Federation credits at a local store. And they will happily remove Federation citizens incarcerated by any world for any reason. Local authorities are not required to cooperate. Starfleet has got this.
