text: Preface
  This manual is primarily written for US Army long-range surveillance units (LRSU) and other Infantry
  reconnaissance and surveillance (R&S) units. It is also provided for use by corps, division, brigade combat
  team (BCT); battlefield surveillance brigade (BFSB); and reconnaissance and surveillance squadron
  commanders and staffs; instructors of US Army corps, division, and BCT intelligence, surveillance and
  reconnaissance (ISR) operations. In addition, many of the subjects covered should be a ready and useful
  reference for other branches of the US Army and US military, and for multinational forces working in a joint
  environment.
  This manual defines the organization, roles, operational requirements, mission tasks, battlefield functions, and
  command and control (C2) relationships of LRSCs organic to the R&S squadron of the BFSB. It also provides
  the doctrine for LRSU to use in combat training and combat. It establishes a common base of tactical
  knowledge from which leaders can develop specific solutions to LRSU tactical problems. It increases the
  effectiveness of LRSU operations by also providing doctrinal principles and selected battlefield-proven tactics,
  techniques, and procedures (TTPs). The Digital Training Management System (DTMS) contains the LRSC
  combined arms training strategies (CATS) and collective tasks for training the LRSU. Before leaders can use
  this manual to develop and execute training for, and to plan, coordinate, and execute LRS missions, they must
  first know FM 3-21.8, Infantry Rifle Platoon and Squad, and LRSC CATS.
