Synopsis as published on the index

To establish policy for the incorporation of a CLS contract as part of the overall sustainment strategy to improve equipment availability and readiness. This Order is in accordance with references (a) through (r). a. CLS can be an effective means to support Marine Corps Ground Equipment and Major Defense Acquisition Program Business Systems. As a support strategy, CLS is normally implemented in one of two ways: (1) Interim Contractor Support (ICS) provides temporary (total or partial) logistics support until a government sustainment capability is provided. ICS does not negate the responsibility to achieve an organic, CLS, or a combined capability as early as practicable; nor does it negate the requirement for testing and evaluation and/or demonstrating the adequacy of a system, equipment, or end-item. (2) CLS is a method of obtaining support for a product at any time throughout its life cycle. CLS dictates that a contractor, rather than the government, is responsible for the integration of logistics support functions such as providing engineering support, identifying requirements for spare and repair parts, facilities, materiel, equipment, training personnel and performing maintenance on weapon systems. Contractors can provide logistics support over a wide range of options, from ICS covering the initial fielding MCO 4200.33A 4 Dec 2020 2 to supporting specific limited operations. CLS may be used for any of the Integrated Product Support Elements (IPSE). b. CLS support for a weapon system can be very diverse. This diversity is often due to each system’s unique mission and economic considerations. Enclosure (1) has example contract tips when considering implementing CLS as part of a sustainment strategy.
