I understand they are the most elite, but that doesn't really address my concerns.
For point #2- If they are the most elite, why do they seem to be everywhere, often alongside regular police? Shouldn't they be reserved for hostage situations and bank robberies?
For point #1- How does them being the most elite justify such armor? They seem basically inhuman, and may as well be godded because anyone with 200+ armor has no chance at all of being killed by a criminal. What's the point of having a unit in the game without a chance of being killed? Maybe only some of the custom classes with ridiculous weapons stand a chance, but 99% of players don't.
