Final answer:
It is false that HIMARS and MLRS are commonly located in a BCT, as these artillery systems are usually part of the Fires Brigade, which supports BCTs with long-range precision fires.
Step-by-step explanation:
It is false that HIMARS (High Mobility Artillery Rocket Systems) and MLRS (Multiple Launch Rocket Systems) are commonly located in a Brigade Combat Team (BCT). Instead, these artillery systems are typically part of the Fires Brigade in the United States Army's modular structure, which provides fire support to BCTs. BCTs are composed of combined arms battalions, including infantry and armored units, and are supported by multiple specialized units, such as aviation, engineer, and military intelligence battalions. However, the Fires Brigade, equipped with systems like HIMARS and MLRS, is a separate entity designed to deliver long-range precision fires and is not organic to a BCT. The HIMARS and MLRS, due to their strategic significance and operational range, are resources that are generally allocated as needed, and they support the BCTs rather than being permanently assigned to them.
