 The bump cap is essentially a tactical ball cap with the plastic insert on the inside. The goal of the plastic insert is to protect people or add some level of protection to mitigate head injuries around the flight line whenever you're working on jets. When it comes to big Air Force changes, things are going to go happen at bases across the world. It kind of hinges on you. Even if it's just wearing a bump cap, it's still cool if you're part of the spearhead of this project. It's cool to see big Air Force taking steps to do something for maintainers or is adding some extra layer of protection to try and make the job better for maintainers because it can be tough, it can be kind of rugged. Somebody trying something to at least make it a little easier and more consistent to come home and not have to worry about head injuries, putting your head open, getting the concussion, being down for however many days and nursing a head.
