Emergency services personnel like law enforcement, firefighters, and EMS can often be seen wearing different pins, medals, citation bars and more on their uniforms, but what do they all mean exactly? The team at Wizard Pins has released a new infographic that outlines as the ultimate guide to pins awarded to emergency services personnel. Not only do you get some great visuals of what all of these badges, medals and more look like, that are placed onto these uniforms, but you also get real detailed descriptions of what they mean and why they're all considered to be high honors for those heroes who receive them. One of these examples would be what's known as the Medal of Meritorious Service, which is specifically given out to those in law enforcement. It's an award that's given to a police officer who was a key part in both rescuing and saving someone for injury, or even worse death, while putting their own life at risk.
