The Source Development Officer at W4GG Hq US Army Tacom plays a pivotal role in advancing the lifecycle management and modernization of ground combat and support vehicle systems for the Department of Defense. Responsible for identifying, evaluating, and engaging industrial partners, this role ensures timely and technically sound procurement of armored vehicle components, tactical wheeled platform systems, and associated ordnance infrastructure. The officer directly supports TACOM’s mission to enhance vehicle survivability, mobility, and power efficiency through integrated acquisition strategies that align with Army modernization priorities. Their portfolio primarily encompasses complex manufacturing and engineering contracts requiring rigorous technical validation and supply chain resilience. The officer maintains sustained relationships with key industrial partners including Schutt Industries, VAREC NV, ONTIC ENGINEERING & MANUFACTURING, INC, A&M AEROSTRUCTURES, INC., and BOWHEAD AVIONICS MANUFACTURING, LLC. These vendors provide specialized capabilities in armored vehicle fabrication, advanced avionics integration, composite structural components, and mission-critical subsystems. The working relationships are characterized by long-term collaboration, technical alignment with Army standards, and frequent engagement in design-to-production contracts requiring compliance with MIL-SPEC and defense logistics protocols. There is no preference for socioeconomic set-asides, with 100% of procurements conducted as full and open competition. This reflects a strategic focus on technical capability and industrial readiness over socioeconomic categorization, prioritizing mission-critical performance and supply chain continuity above targeted small business participation. The officer’s procurement focus is overwhelmingly centered on NAICS 336992—Military Armored Vehicle, Tank, and Tank Component Manufacturing—accounting for 75.4% of activity, with additional emphasis on NAICS 339999 for specialized manufacturing of defense-related components. Expertise lies in procuring armored hulls, suspension systems, powertrain integrations, and survivability upgrades for platforms such as the Stryker and Bradley families, demanding deep familiarity with ballistic protection standards, electromagnetic compatibility, and military-grade materials engineering.
