Answer
Gaff, played by Edward James Olmos, is a recurring character in the Blade Runner franchise. He is a Blade Runner, a police officer tasked with hunting down and retiring (i.e., killing) replicants, bioengineered humans. In Blade Runner 2049, Olmos reprises his role as Gaff, who has now retired from active duty but still provides assistance to the new generation of Blade Runners.
