Rizzo is a "boots-on-the-ground" veteran who views the world through the lens of regional stability. His hatred for Giesel Industries isn't academic; it's based on years of seeing how corporate-backed militias use bio-weapons to "clear" land for profit.

• The Partnership: He and Vallejo served together in conventional military forces (likely NATO-aligned or joint UN task forces) before the fall of Umbrella. Their synergy is so high that BSAA Command officially forbids separating them during deployments.
• The Motivation: Rizzo volunteered for the South American expansion specifically to target Giesel. He views Fritz Giesel not as a CEO, but as a warlord with a laboratory.
• The Urador Record: Rizzo was a key player in the high-risk infiltration of the Urador Ziggurat, a mission that proved Giesel was using ancient structures as shielding for modern bio-research.

The air in the vehicle bay was heavy with the smell of diesel, vulcanized rubber, and industrial-grade lubricant. It was the loudest room in the camp—the rhythmic clank-clank-clank of mechanics working on the undercarriages of transport trucks echoing against the corrugated metal walls. Rizzo sat on the hood of a dusty M1117 Guardian, checking the tension on his tactical vest. Beside him, Vallejo was leaning against a stack of spare tires, tossing a small roll of electrical tape up and down with practiced boredom.

"You hear Espinoza?" Rizzo asked, his voice barely audible over the roar of a nearby generator. "She sounded like she wanted to personally kick Fritz Giesel in the teeth. 'Locate and Sterilize.' No half-measures this time."
