Chapter 1 1-10 ATP 4-90 18 June 2020 The S-2 is responsible for preparing paragraph 1, 1a, 1b, 1b(1), 1b(2), 1c, and 1f of the BSB operation order. The S-2 prepares annex B, including all appendices, for attachment to the operation order as required. S-3 Section The S-3 is the principal staff officer responsible for movement and maneuver of the BSB including development of plans and operations. The S-3 synchronizes and integrates BSB current operations, including support operations, with the other warfighting functions in time, space and purpose. This is executed across the planning horizons of the integrating cells in accordance with the commander’s intent. The S-3 coordinates with all other staff officers and section during the development of plans and orders to ensure synchronization. See chapter 2 for more information on integrating cells, warfighting functions, and planning horizons. The S-3 section translates external support requirements established by the SPO into missions for the BSB units. The S-3 accomplishes this by preparing, publishing and distributing written orders (warning, operations, and fragmentary) to subordinate units for execution. The S-3, with the information provided by the SPO, develops key paragraphs of the operation order; references, time zone, task organization, paragraphs 1, 1a, 1b, 1d, 1e, paragraph 2, paragraph 3, and paragraph 5. The S-3 prepares annex A (task organization), C (operations), D (fires), E (protection), and other annexes for attachment to the operation order as required. The S-3 develops running estimates to ensure operations are achieving the desired effect and makes adjustments to the operation as necessary. The S-3 develops the unit task organization to support operations, plans and executes operations security. The S-3 section also maintains situational awareness and tracks the BCT’s operations as well as maintains the battalion’s common operational picture. The S-3 section plans tactical troop movements and is responsible for determining route selection, priority of movement, timing, security, quartering, staging, and preparing movement orders. After the BCT terrain manager provides the BSB with a brigade support area, the BSB S-3 recommends a specific location within it for the BSB and its subordinate elements in coordination with the BSB XO and SPO. In accordance with the BSB commander’s guidance, the BSB S-3 develops the BSA defensive plan. Support Operations The BSB SPO is the principal staff officer responsible for planning and synchronizing all BSB sustainment operations to support units assigned or attached to the BCT. Support operations is the staff function of planning, coordinating, and synchronizing sustainment in support of units conducting decisive action in an area of operations (ATP 4-93). This includes supply, distribution, maintenance, and medical support. Although the SPO section is separate from the battalion S-3, the SPO section is fundamentally part of BSB operations. The SPO collaborates closely with the S-3 staff during the operations process to support the MDMP and orders development. The SPO also collaborates with the BSB S-3 to ensure the operations to sustain the BCT are integrated across all warfighting functions and with the BCT concept of operations. The SPO and his staff develop significant portions of the BSB operation, warning, and fragmentary orders. The SPO provides information to support development of the BSBs mission and execution paragraphs to include commander’s intent, concept of operations, and scheme of movement, and tasks to subordinate units. This includes plans to execute supply support activities, supply distribution, maintenance and recovery support allocation, medical operations, and medical logistics distribution. The SPO also describes sustainment information systems support. The BSB SPO planning horizons include mid-range future operations and short range planning and execution. The SPO develops a sustainment plan by understanding and applying BSB sustainment capabilities against brigade’s sustainment requirements. The brigade S-1, S-4 and brigade surgeon communicate sustainment requirements using various methods. The primary method is through development of paragraph 4, Sustainment, and annex F of the BCT operation order. The BCT S-4 is responsible for developing these portions of the order. Other methods of communicating sustainment requirements include daily logistic status reports, running estimates, mission analysis, and verbal reports. Sustainment requirements determination covers all elements of sustainment: logistics, Army health system, human resources, and financial management/comptroller operations. This information is consolidated by the BCT S-4 and passed to the BSB SPO. The BSB SPO advises the BSB commander on support requirements, assets available, shortfalls, and mitigation strategies. The SPO incorporates all combat unit requirements, unit
