About the company
Defense Services Group, LLC, a small-business sole proprietorship based in Lakeside, California, provides fire suppression system and air conditioning maintenance and repair services for tactical vehicles to the United States Marine Corps and Marine Corps Air Ground Combat Center as a prime contractor (73% of recent awards) and as a subcontractor on military vehicle and equipment repair work under defense primes.
Defense Services Group operates as a Total Small Business set-aside contractor across its prime footprint. The vendor's customer base concentrates heavily on Marine Corps programs. The top five customer organizations by award count account for 87% of recent awards, led by the United States Marine Corps (8 awards, $1.2 million combined potential value) and the Marine Corps Air Ground Combat Center (2 awards, $1.4 million combined potential value), with subordinate activity from the Department of the Navy and Department of the Army. The two rankings align closely — Marine Corps dominates both volume and dollars — and represent 91% of combined potential value obligated across the portfolio.
Defense Services Group's core capability centers on fire suppression and air conditioning system maintenance and repair for armored tactical vehicles. The vendor holds two prime contracts with MCAGCC Twentynine Palms: a base-year purchase order awarded January 11, 2023, for $1.09 million with four one-year option periods and a possible six-month extension, and a subsequent purchase order awarded April 1, 2026, for $283,448.76 with ultimate completion March 31, 2027. Both contracts require the vendor to maintain 92 percent or greater operational readiness across approximately 1,600 tactical vehicles (BAE RG33, BAE Caiman, Force Protection, General Dynamics RG31, Navistar, and MATV variants), with personnel holding Secret clearances and U.S. citizenship. The vendor also provides engine repair and maintenance services through subcontracts with Raytheon Company, Vertex Aerospace LLC, HII Fleet Support Group LLC, and Delphinus Engineering, Inc., covering small-boat engine repair, integrator repair or return services, and embedded maintenance logistics support.
Activity has remained low and episodic — one award in 2023, two in 2024, and two in 2025 — with the two awards (combined potential value $1.4 million) facing recompete in the next twenty-four months. Total combined potential value across fifteen awards since 2010 is $2.7 million, with $2.5 million obligated to date. The vendor places work on an indefinite delivery contract designated M6700421D0002 (2 task orders) and subordinate vehicles with the Marine Corps and Navy.
