This report details the decision process for the recommendations of conceptual future indirect fire systems supporting this estimate. Value-focused thinking (VFT) and preference ranking among subject matter experts were employed to formulate these recommendations. MARCUS, developed by the Central Operational Research Team (CORT), was used to obtain a consensus rank order in each criterion, as well as an aggregate rank order across all criteria. Schools of Thought Analysis was used to identify potentially diverging opinions among the participants. Typically, strong agreement existed among participant subject matter experts. The group was unanimous in recommending a 155mm Lightweight Towed Howitzer as the focal point of the Army's future indirect fire assets. The majority of the group also recommended continued use of the 81mm mortar although modernization of this weapon is considered beneficial. The group also believes in the acquisition of some type of missile, although strong agreement could not be obtained as to whether the optimal missile system is centralized or decentralized. The results of this activity have been briefed to the VCDS. A letter of interest by the Directorate of Land Requirements (DLR) has since been issued, anticipating t
