The Tactical Logistics Distribution System (T.LoaDS or TLoaDS) is a powerful and flexible simulation application for assessing current or future tactical or sea-based distribution systems. In its current state of development, it is an analytical model for assessing the pros and cons of new doctrine, distribution techniques, organizational structures, and equipment concepts. It can also be used to find out how to best use available resources to sustain a military force in a wide variety of scenarios. The "System" in TLoaDS refers to its modular architecture and that it is more that just a simulation. It is a suite of analytical study tools. This paper introduces TLoaDS features by an examination of its current software module architecture. It also covers a few of the modules under development to expand TLoaDS scope, depth and range of use, and further improve its ease of use.
