Visor Version Filecard information: File Name: McCarthy, David B.SN: 500-63-0163Primary Military Specialty: Mechanized Recon Secondary Military Specialty: Special ServicesBirthplace: Boston, MassachusettsGrade: E-5 (Sergeant)Blocker drove a taxi in Boston for three years. After seven armed robberies, three backseat births, and one near-fatal plunge through a collapsing roadway, he decided it was safer to drive something armor-plated with the ability to shoot back. He is qualified to drive every wheeled vehicle in the Army inventory and was the test driver for a half dozen prototype vehicles at Aberdeen Proving Grounds."I've seen him go over into a complete roll at high speed, recover and keep on going. He takes on the slalom minimally at 85 mph and doesn't tip nary a cone. The skid pad? Don't even ask. All that and he does it with vehicles built to military specs. Amazing!"
