Secret Service Uniformed personnel, Border Patrol, Force Protective Services are Fed law enforcement officers, and there are Fed Prison guards, they have different retirement options then say a clerk at HHS. I am guessing that would include the Capital Police as well. We’ve had uniformed Federal Law Enforcement types for a very long time, what do you find wrong with that?

That military forces have a completely different mindset than any civil officers: kill or subdue the enemy.
Or rather, that was a difference. Looking at LEOs today I'm not sure that's really a difference: the enemy is us.
