US Army: Outline TOs NBC Units

v. 1.0 July 22, 2001

M. Eric Fourcade

The TOs given here are from US Army FM 3-101 which may be viewed at www.adtdl.army.mil The TOs appear to have changed in 2000, but the new ones are not as yet available.

As a general outline of US NBC units, the following quotations below from FM 3-101 are helpful. For NBC units, the brigade and battalion HQs control varying numbers of specialized companies which are assigned as required. We include a rough guide to allottment of companies.

CHEMICAL UNIT ORGANIZATIONS

CHEMICAL UNITS

The mission of chemical units is to provide decon, NBC reconnaissance, large-area smoke, and staff support to commanders to enhance their warfighting capabilities or support contingency requirements. Most chemical units are 100 percent mobile. Basis of allocation is determined on the number and type of units being supported and METT-T.

CHEMICAL BRIGADE

The chemical brigade normally supports a corps and consists of a brigade headquarters and headquarters company (HHC) and two to six chemical battalions. The brigade HHC consists of the brigade headquarters, containing the commander's immediate staff (S1, S2, S3, S4, and communications) and the headquarters company, which provides administrative and logistical support to the headquarters.

CHEMICAL BATTALION

The chemical battalion consists of a battalion headquarters and headquarters detachment (HHD) and two to five chemical companies. The battalion headquarters contains the battalion commander's principal staff (S1, S2/3, S4) and the headquarters detachment, which provides administrative and logistical support to the headquarters.

There are two types of chemical battalion headquarters. One is designed to operate as part of a chemical brigade. The other, the chemical battalion (enhanced) (theater army), is designed to be assigned to a theater army area command (TAACOM), and to be the senior chemical headquarters in that command.

CHEMICAL COMPANIES

Chemical Decontamination Company

The chemical decon company provides equipment decon support to units. The company consists of a company headquarters, a maintenance section, and five decon platoons. The company is 100 percent mobile. Each decon platoon is organized with a platoon headquarters and three decon squads. The decon squads are equipped with the M12A1 power-driven decon apparatus (PDDA).

Motorized Smoke Generator Company

The motorized smoke generator company provides large-area smoke support for tactical operations. The company consists of a company headquarters, a maintenance section, two smoke platoons, and a support platoon. The company is 100 percent mobile. Each smoke platoon is organized with a platoon headquarters, and three smoke squads. The smoke squads are equipped with the motorized smoke system. The support platoon may operate in a centralized or decentralized mode. When the company is organized to conduct company-level smoke operations, the support platoon operates as a platoon under the control of the support platoon leader. In decentralized operations, smoke platoons operate independently with support squads task-organized to each platoon under control of the smoke platoon leader.

The motorized smoke company is normally assigned to a chemical battalion, but may operate in direct support to a division. Motorized smoke units are less survivable than mechanized smoke units. This must be considered when determining how far forward motorized smoke units will operate.

The smallest deployable element of the company is a platoon. A motorized smoke platoon can create a smoke haze from 1,100 to 2,800 meters in width. FM 3-50, Smoke Operations provides more detailed information concerning smoke operations.

Mechanized Smoke Generator Company

The mechanized smoke company provides large-area smoke support for tactical operations in the forward combat area. The company consists of a company headquarters and two smoke platoons. The company is 100 percent mobile. Each platoon consists of a platoon headquarters, two smoke squads, and a support squad. The smoke squads are equipped with M1059 mechanized smoke vehicles. The M1059 allows them to provide more responsive smoke support to armored and mechanized infantry units.

The smallest deployable element of the mechanized company is a platoon. One platoon can create a smoke haze from 600 to 1,500 meters in width. Survivability of the fuel support platoon/ squads must be taken into consideration during planning. FM 3-50, Smoke Operations provides detailed information concerning smoke operations.

Smoke/Decontamination Company

The smoke/decon chemical company (corps/theater army) provides large area smoke and equipment decon support to divisions, units in the corps rear areas, or COMMZ. The company consists of a company headquarters and four smoke/decon platoons. The company is 100 percent mobile. Each platoon consists of a platoon headquarters, two smoke/decon squads, and a fuel/water support squad. The smoke/decon squads are equipped with M17 lightweight decon systems (LDS) and motorized smoke system. Each support squad can haul 2,400 gallons of water and 1,100 gallons of fog oil.

Each platoon can provide equipment decon and large area smoke generation support, however, the platoons cannot perform these missions simultaneously. Platoons cannot immediately switch from one mission to the other and must plan changes to mission configuration in detail.

A platoon can provide smoke haze from 550 to 1,400 meters in width. When the platoon is configured for decon support it can establish two operational decon sites or one thorough decon site.

NBC Reconnaissance Company

The NBC reconnaissance company provides NBC reconnaissance support through the area of operations to locate, identify, mark, report NBC contamination, and identify bypass routes around contaminated areas. The company has three platoons, each with four recon squads. The company is 100 percent mobile. Each squad contains two recon teams.

The NBC reconnaissance company is normally assigned as a separate company of the chemical brigade, but may be attached to a chemical battalion. The company's platoons can conduct NBC reconnaissance, surveys, surveillance, sampling, and limited conventional reconnaissance missions throughout the corps area of operations. Recon squads may also locate potential decon sites. FM 3-19, NBC Reconnaissance, provides detailed information concerning NBC reconnaissance operations.

Chemical Company (Smoke/Decontamination/Reconnaissance)

This company provides equipment decon, NBC reconnaissance, large-area smoke, and chemical staff support to armored cavalry regiments (ACR). The company consists of a chemical staff section, a company headquarters, one NBC recon platoon, and one smoke/decon platoon. The company is 100 percent mobile.

The company headquarters has a headquarters section and a maintenance section. The NBC reconnaissance platoon is organized with a platoon headquarters and three reconnaissance squads, each with two recon teams. The smoke/decon platoon is organized with a platoon headquarters, two smoke/decon squads, and a support squad. The smoke/decon platoon is equipped with M1059 mechanized smoke vehicles and M17 LDS. The M1059 is in the smoke/decon squads, and the M17 LDS is in the support squad.

The smoke/decon platoon performs missions similar to the platoons of the smoke/decon company with the same considerations for planning. During offensive operations or operations forward in the covering force area or main battle area, thorough decon operations will probably not be conducted; however, assets may be required to augment operational decon operations. Recon assets, operating forward, locate uncontaminated avenues of approach and contaminated areas that need to be reported to and avoided by follow-on forces.

Heavy Division Chemical Company

The heavy division chemical company provides equipment decon, NBC reconnaissance, large-area smoke, and chemical staff support to armored and mechanized infantry (heavy) divisions. The company is organized with a division chemical section, an NBC center, a company headquarters, four decon platoons, a mechanized smoke platoon, and an NBC reconnaissance platoon. The company is 100 percent mobile.

The division chemical officer has operational control (OPCON) of the company and advises the division commander on NBC defense procedures and on the employment of chemical unit assets. The specific responsibilities and functions of the division chemical section are discussed later in this chapter.

The company headquarters contains a headquarters section and a maintenance section. Each decon platoon is organized with a platoon headquarters and three decon squads. The smoke platoon is comprised of a platoon headquarters, two smoke squads, and a support squad. The reconnaissance platoon is organized with a platoon headquarters and three reconnaissance squads, each with two recon teams.

The company must be organized to employ its platoons to permit rapid response to changing situations based on the tactical scheme of maneuver and METT-T.

The decon platoons may conduct thorough decon operations in the brigade and division rear area or they may support operational decon efforts forward of the brigade rear boundary. Decon platoons may be required to operate away from the company headquarters for extended periods of time. It is essential that communications, administration, and logistics be planned in detail to maximize support.

The mechanized smoke platoon supports maneuver forces in the forward combat area. The platoon is equipped with M1059 mechanized smoke vehicles and can provide a smoke haze 600 - l,200 meters in width. If the division is being supported by a mechanized smoke company, the divisional smoke platoon may be placed under the control of the smoke company.

The NBC recon platoon primarily supports efforts for contamination avoidance within the division. The platoon conducts NBC reconnaissance, surveys, surveillance, sampling, and limited conventional reconnaissance missions. The platoon functions are similar to those of platoons in the NBC reconnaissance company.

Chemical Company (Airborne/Air Assault)

The chemical company (airborne/air assault) provides equipment decon, large-area smoke, and chemical staff support to the airborne and air assault divisions. The company is organized with a division chemical section, an NBC center, a company headquarters, and three smoke/decon platoons.

The division chemical officer has operational control (OPCON) of the company and advises the division commander on NBC defense procedures and on the employment of chemical unit assets. The specific responsibilities and functions of the division chemical section are discussed later in this chapter.

The company headquarters contains a headquarters section and a maintenance section. The smoke/decon platoons contain a platoon headquarters, two smoke/decon squads, and a support squad.

Each platoon can provide equipment decon and large-area smoke generation support; however, the platoons cannot perform these missions simultaneously. Platoons cannot immediately switch from one mission to the other and must plan changes to mission configuration in detail.

A platoon can provide smoke haze from 550 to 1,400 meters in width. When the platoon is configured for decon support it can establish two operational decon sites or one detailed equipment decon (DED) station.

CHEMICAL SERVICE ORGANIZATIONS

Chemical service organizations provide NBC reconnaissance, decon, and staff support to units where these capabilities do not exist or are inadequate. These units are normally assigned or attached to separate brigades, corps, theater army area commands, and theater army units to provide NBC support across a wide range of capabilities. The chemical service organizations are 100 percent mobile using organic vehicles.

Chemical service organizations depend on the supported unit for administrative and logistical support. All of these units are 100-percent air mobile.

Chemical Team FA (Decontamination)

The FA team provides equipment decon support for installations located behind the division rear boundary or to separate brigades. The team is organized with a headquarters section and three decon squads. The squads can operate one detailed equipment decon station collectively or three operational decon sites separately.

Chemical Team JA (NBC Element)

The JA team provides NBC staff support to augment separate brigades, corps, theater defense brigades, theater armies, and unified commands. It is organized to provide staffing for one 12-hour shift. Responsibilities and functions will normally include operating the NBC warning and reporting system (NBCWRS) and monitoring the status of the command's NBC defense procedures and chemical assets. However, the team may also be responsible for coordinating specific actions dependent on the level of command.

Chemical Team JB (NBC Element)

The mission of the JB team is identical with that of the JA team. The JB team is organized to provide two 12-hour shifts. The basis of allocation is one per area support group, TAACOM, and selected separate brigades.

Chemical Team LA (Reconnaissance)

The mission of the LA team is to provide NBC reconnaissance support to separate brigades and theater defense brigades. It collects, examines, and identifies NBC contamination, but has limited capability to evaluate data.

Chemical Team LB (Reconnaissance)(Special Forces)

The mission of the LB team is to provide NBC reconnaissance support to Special Forces (SF) units. This support will be in the form of technical expertise about NBC systems and employment tactics, techniques, and procedures. Each of these airborne qualified special chemical reconnaissance teams is assigned to an SF Group.

The special chemical reconnaissance team is employed in one of three modes--unilaterally in a permissive environment; as an augmentation for a Special Forces Operational Detachment-Alpha (SFODA), or as trainers for SFODAs deploying into denied areas. The special chemical reconnaissance team receives additional chemical reconnaissance and SF-related training and is familiar with SF-unique procedures. The team is uniquely suited for rapid world-wide deployment. See FM 3-18, Special Forces NBC Reconnaissance (LB) Team.
