A police uniform created to be distinctive and easily recognized for civilian aid. Protected with a kevlar vest and a lightweight aluminum chest plate, these units are well armored and are trained to counter terrorist if needed.
The design vaguely, and I do mean vaguely, reminds me of the armor that the Judges wear in Judge Dredd. I have no idea why though, but I've got to ask - why not just design the aluminum chest plate to cover the abdominal muscles as well? The bottom part of the torso I mean. Still I like the helmet's design and the lights on the chest plate - gives it a sense of practicality.
I really like the approach that Elysium took with the faceless robot soldiers but its always better to have human mentality about what is right or wrong. I wanted this officer to still have that ability human to care about the people they are trying to protect and feel hardships they go through during their daily life. Underneath all that armor, he is just one of the people in society.
