For many years, from roughly 2004 through 2017, Tank-automotive and Armaments Command referred to itself as TACOM Life Cycle Management Command.In late 2017, the command began an ongoing effort to discontinue the use of LCMC in most circumstances.In an email memorandum sent on Oct. 31, 2017, Col. Jeffrey Witt, the TACOM chief of staff, wrote:"We had the Historian do some research to help us clarify our organizational designation in an effort to preclude confusion and add consistency to our messages, records, correspondence, etc. Many of us have reverted to using 'TACOM LCMC' or 'TACOM Life Cycle Management Command' when we really should be using 'US Army Tank-automotive and Armaments Command' or 'TACOM'. It is important for Army Organizations to issue orders and maintain official records under their official Command Designation."Witt also wrote, "Official command documents -- including regulations, memoranda, executive correspondence, and orders -- should use 'US Army Tank-automotive and Armaments Command.' 'TACOM LCMC' is an inaccurate title for these functions and can lead to confusion and loss of credibility since 'TACOM LCMC' is not an 'official' Army command organization."The June 6, 2019 "Very brief history of U.S. Army Tank-automotive and Armaments Command (TACOM)" Information Paper from the TACOM History Office briefly explains the origin of the LCMC naming convention.The paper explains that TACOM began using LCMC in 2004 when the AMC Commanding General and Assistant Secretary of the Army for Acquisition, Logistics, and Technology "attempted to create a layer of integrated rating chains for senior leaders" and "called these augmentations to existing command structures 'life cycle management commands.'"The paper goes on to explain that, "within a year the integrated rating chains were withdrawn" and in 2009, the commands "nuanced the 'LCMC' term into a 'materiel enterprise.'"While TACOM still functions as one of AMC's life cycle management commands, that functional role is not part of the command's official name.
