- "...which is what happens when you call the feds..."
- ―Malcolm Reynolds
Colloquially known as "the feds", federal agents are the law enforcement arm of the Union of Allied Planets.
Agent McGinnis, a federal agent with the rank of marshal, was the leader of a "small battery" of feds at Saint Lucy's hospital who managed to briefly apprehend River & Simon Tam and Jayne, but lost them again.
Most of the weapons they use are non-lethal, like the sonic rifles, as well as other weapons and gear, making them very different from the specialized Hands of Blue.
