The Misconception.
Anyone who has been on a Half Life 2 Roleplay Server knows exactly what a Civil Protection Unit is. They're augmented, near-robotic badasses who can shrug off bullets like pinches. They are pointlessly mean to citizens just because they're in a bad mood. They shoo people away from park benches if they stop to sit down for a moment. They never go offline, constantly wandering the streets, patrolling for minor crimes to beat people to a pulp for. Their masks and vocoders reflect their actual personalities; inhuman and robotic.
Right?
Wrong.
Units in the CPA are just as human as the citizens, if not more so. They are forced to try and reclaim their humanity every day, trying desperately to connect with their peers to avoid becoming no more than a mask and a number. As they rank up, more and more is demanded of them. They are forced to become role models for the recruits, and corralled even farther by the Union and forced to commit more and more crimes against the people who were once their friends. They show no emotion not because they have no emotion to show, but because should they reveal that they are weak to the populace, either the CPA or the people themselves will punish them for it. Their masks do not protect their faces so much as their identities, as to reveal your status as a Unit to the populace could be to condemn you to death at their hands. Under all of those straps, buckles, bullet resistant layers and trauma pads, they are no better than any citizen.
However, the citizens don't know that. This fact is very important. Everything about the CPA is designed to hide their humanity from the citizens. Union High Command wants them to be afraid of the CPA, even if the Units themselves feel like monsters because of it. More than anything, they're forced to fill a role. They are told that they should act a certain way, and they do. They pretend to be big and scary, until eventually it's not pretending any more. Eventually your duties as a Unit grow beyond the point that you can find time for yourself as a human, and you become what you once hated. And once that time comes, you look at yourself in the mirror and all that's left is the mask, and those two cold, reflective lenses, and that's too much for some people.
So, do you still feel like applying for CPA?
