Mariellen Crosson

Mariellen Crosson serves as a Contracting Officer with the W4MM USA Joint Munitions Command, where she plays a pivotal role in securing mission-critical capabilities to sustain the U.S. Army’s conventional ammunition and explosives lifecycle. Responsible for end-to-end acquisition execution, she manages complex procurements spanning system modernization, logistics support, and demilitarization services, ensuring operational readiness across land, air, and naval forces. Her portfolio emphasizes technical solutions that enhance supply chain resilience and warfighting effectiveness, with a focus on compliant, risk-managed contracting aligned with Department of Defense acquisition regulations. Crosson engages with a diverse array of contractors, primarily in the information technology and defense electronics sectors, fostering partnerships with firms capable of delivering secure, interoperable systems. While no single vendor dominates her award profile, her contracting patterns reflect consistent collaboration with specialized providers in computer systems design, communications equipment manufacturing, and IT wholesale distribution. She prioritizes vendors with proven expertise in defense-grade cybersecurity, ruggedized hardware, and logistics automation, ensuring solutions meet stringent military standards. Crosson’s contracting activity is entirely non-set-aside, with 100% of her acquisitions conducted under full and open competition. This reflects a strategic alignment with the Joint Munitions Command’s need for rapid, scalable access to high-capacity industrial base capabilities, rather than socioeconomic set-asides. While she does not routinely utilize 8(a), HUBZone, or SDVOSB programs, her approach ensures rigorous evaluation of technical merit, past performance, and compliance with defense acquisition standards. Her primary procurement focus lies in NAICS 541512 (Computer Systems Design Services), 334220 (Radio and Television Broadcasting and Wireless Communications Equipment Manufacturing), and 423430 (Computer and Computer Peripheral Equipment and Software Merchant Wholesalers). She specializes in acquiring secure command and control systems, embedded communications hardware, and integrated logistics software platforms essential to modern munitions management and battlefield sustainment.
