FM 17-15 Chapter 1 ORGANIZATIONS (2024)

CHAPTER 1
INTRODUCTIONThe fundamental mission of the tank platoon is to close with and destroy the enemy. The platoon's ability to move, shoot, communicate, and provide armored protection is a decisive factor on the modern battlefield. It moves, attacks, defends, and performs other essential tasks to support the company team or troop mission. In accomplishing its assigned missions, the platoon uses fire, maneuver, and shock effect, synchronized with other maneuver elements and with combat support (CS) and combat service support (CSS) assets. When properly supported, it is capable of conducting sustained operations against any sophisticated threat.

The tank platoon can survive and win in battle, however, only if it is well trained, effectively led, and highly motivated. Crews must be aggres-sive, and their tactics must reflect the tempo and intensity of maneuver warfare. Platoon training must prepare them to operate in hostile territory with the enemy to their front, flanks, and rear.

The Tank Platoon

By itself, any tank can be vulnerable in the face of diverse battlefield hazards (such as enemy forces or unfavorable terrain) and situations; these vulnerabilities are significantly reduced when tanks are employed as units.

The tank platoon is the smallest maneuver element within a tank com-pany. Organized to fight as a unified element, the platoon consists of four main battle tanks organized into two sections, with two tanks in each section. The platoon leader (Tank 1) and platoon sergeant (Tank 4) are the section leaders. Tank 2 is the wingman in the platoon leader's section, and Tank 3 is the wingman in the platoon sergeant's section (see Figure 1-1).

The tank platoon is organic to tank companies and armored cavalry troops. The platoon may be cross-attached to a number of organizations, commonly a mechanized infantry company, to create company teams. It may also be placed under operational control (OPCON) of a light infantry battalion.

Under battlefield conditions, the wingman concept facilitates control of the platoon when it operates in sections. The concept requires that one tank orient on another tank on either its left or right side. In the absence of specific instructions, wingmen move, stop, and shoot when their leaders do. In the tank platoon, Tank 2 orients on the platoon leader's tank, while Tank 3 orients on the platoon sergeant's tank. The platoon sergeant (PSG) orients on the platoon leader's tank. (See Figure 1-2.)

The Tank Company

The tank company is organized, equipped, and trained to fight pure; it can also be task organized by higher headquarters to fight with infantry as a company team. The tank company consists of a headquarters and three tank platoons. The company headquarters is equipped with two tanks, one M113A2 armored personnel carrier (APC), two M1025 or M998 high-mobility multipurpose wheeled vehicles (HMMWV), and one cargo truck with a 400-gallon water trailer (see Figure 1-3, page 1-4). A maintenance section from the battalion maintenance platoon is normally attached to the tank company. The maintenance section consists of one APC, one heavy recovery vehicle, and one utility truck with trailer carrying spare parts based on the prescribed load list (PLL). A medic, normally attached from the battalion medical platoon, travels in another APC.

The Armored Cavalry Troop

The cavalry troop is organized, equipped, and trained to protect and conserve the combat power of other combined arms forces. While its primary missions are reconnaissance and security, the cavalry troop may be called upon to execute attack, defend, and delay missions as part of squadron and regimental missions.

The armored cavalry troop consists of a headquarters, two tank pla toons, two scout platoons, and mortar and maintenance sections. The headquarters section is equipped with one main battle tank, one command post (CP) carrier, one APC, one cargo truck, and two utility trucks. The scout platoons consist of six M3 cavalry fighting vehicles (CFV). Equipment in the mortar and maintenance sections includes two 107-mm mortars mounted in self-propelled carriers, one APC, one heavy recovery vehicle, ers. (See Figure 1-4.)

The light armored cavalry troop has the same basic configuration. The main battle tanks are replaced by the M8 armored gun system (M8-AGS); instead of M3s, there are 10 M1025 or M1026 HMMWVs in each platoon. The mortars are towed by M1025 HMMWVs. For additional information, refer to FM 17-97.

NOTE: For information on light infantry organizations, refer to Appendix B of this manual and to FM 7-20. Additional information concerning task organized company teams is in Appendix B and in FM 71-1.

The tank crew is a tightly integrated team. Though all members have primary duties, success depends on their effectiveness as a crew. They must work together to maintain and service their tank and equipment, and they must function as one in combat. Crews must cross-train so each member can function at any of the other crew positions.

Platoon Leader

The platoon leader is responsible to the commander for the discipline and training of his platoon, the maintenance of its equipment, and its success in combat. He must be proficient in the tactical employment of his section and of the platoon in concert with a company team or troop. He must have a solid understanding of troop-leading procedures and develop his ability to apply them quickly and efficiently on the battlefield.

The platoon leader must know the capabilities and limitations of the platoon's personnel and equipment; at the same time, he must be well versed in enemy organizations, doctrine, and equipment. He must serve as an effective tank commander (TC). Most important of all, the platoon leader must be flexible, using sound judgment to make correct decisions quickly and at the right times based on his commander's intent and the tactical situation.

Platoon leaders must know and understand the task force mission and the task force commander's intent. They must be prepared to assume the duties of the company commander in accordance with the succession of command.

Platoon Sergeant

The PSG is second in command of the platoon and is accountable to the platoon leader for the training, discipline, and welfare of the soldiers in the platoon. He coordinates the platoon's main tenance and logistics requirements and handles the personal needs of individual soldiers. The PSG is the most experienced TC in the platoon. His tactical and technical knowledge allow him to serve as mentor to crewmen, other NCOs, and the platoon leader. His actions on the battlefield must complement those of the platoon leader. He must fight his section in concert with the platoon leader's section.

Tank Commander

The TC is responsible to the platoon leader and signed equipment, the reporting of logistical needs, and the tactical employment of his tank. He briefs his crew, directs the movement of the tank, submits all reports, and supervises initial first-aid treatment and evacuation of wounded crewmen. He is an expert in using the tank's weapon systems, requesting indirect fires, and executing land navigation.

The TC must know and understand the company mission and company commander's intent. He must be prepared to assume the duties and responsibilities of the platoon leader or PSG in accordance with the succession of command. These requirements demand that the TC maintain situational awareness by using all available optics for observation, by eavesdropping on radio transmissions, and by monitoring the intervehicular information system (IVIS) or appliqué digital screen (if available).

Gunner

The gunner searches for targets and aims and fires both the main gun and the coaxial machine gun. He is responsible to the TC for the maintenance of the tank's armament and fire control equipment. The gunner serves as the assistant TC and assumes the responsibilities of the TC as required. He also assists other crewmembers as needed. Several of his duties involve the tank's communications and internal control systems: logging onto and monitoring communications nets; maintaining digital links if the tank is equipped with the IVIS or appliqué digital system; inputting graphic control measures on digital overlays; and monitoring digital displays during the planning and preparation phases of an operation.

Driver

The driver moves, positions, and stops the tank. While driving, he constantly searches for covered routes and for covered positions to which he can move if the tank is engaged. He maintains his tank's position in formation and watches for visual signals. If the tank is equipped with a steer-to indicator, the driver monitors the device and selects the best tactical route. During engagements, he assists the gunner and TC by scanning for targets and sensing fired rounds. The driver is responsible to the TC for the automotive maintenance and refueling of the tank. He assists other crewmen as needed.

Loader

The loader loads the main gun and the coaxial machine gun ready box; he aims and fires the loader's machine gun (if the vehicle is equipped with one). He stows and cares for ammunition and is responsi ble to the TC for the maintenance of communications equipment. Before engagement actions are initiated, the loader searches for targets and acts as air or antitank guided missile (ATGM) guard. He also assists the TC as needed in directing the driver so the tank maintains its position in forma tion. He assists other crewmembers as necessary. Because the loader is ideally positioned both to observe around the tank and to monitor the tank's digital displays, platoon leaders and TCs should give strong consid eration to assigning their second most experienced crewman as the loader.

NOTE: On the M8-AGS, the function of loading the main gun is handled by the autoloader. Loading of the coaxial machine gun, as well as the stowage and care of ammunition, becomes the duty of the gunner. The absence of a loader also means the TC assumes a greater degree of responsibility for air and ATGM watch.

To win in battle, leaders must have a clear understanding of the capabilities and limitations of their equipment. Figures 1-5 through 1-9, pages 1-9 through 1-13, list the specifications, characteristics, and significant features of the M60A3 and M1-series main battle tanks and the M8-AGS. These listings will assist the platoon leader in evaluating transportability, sustainment, and mobility considerations for his own vehicles and for those with which the platoon may operate as part of a company team or troop.

Capabilities

Tanks offer an impressive array of capabilities on the modern battlefield: excellent cross-country mobility, sophisticated communica tions, enhanced target acquisition, lethal firepower, and effective armor protection. In combination, these factors produce the shock effect that allows armor units to close with and destroy the enemy in most weather and light conditions. Tanks can move rapidly under a variety of terrain conditions, negotiating soft ground, trenches, small trees, and limited obstacles. In addition, global positioning systems (GPS) and inertial position navigation (POSNAV) systems allow today's tanks to move to virtually any designated location with greater speed and accuracy than ever before. Use of visual signals and the single channel ground/airborne radio system (SINCGARS) facilitates rapid and secure com munication of orders and instructions. This capability allows tank crews to quickly mass the effects of their weapon systems while remaining dispersed to limit the effects of the enemy's weapons. On-board optics and sighting systems enable the crews to acquire and destroy enemy tanks, armored vehicles, and fortifications using the main gun or to use machine guns to suppress enemy positions, personnel, and lightly armored targets. The tank's armor protects crewmembers from small arms fire, most artillery, and some antiarmor systems.

Limitations

Tanks require extensive maintenance, proficient operators, and skilled mechanics, as well as daily resupply of large quantities of bulky petroleum products such as fuel, oil, and grease. They are vulnerable to the weapons effects of other tanks, attack helicopters, mines, ATGMs, antitank guns, and close attack aircraft. When tanks operate in built-up areas, dense woods, or other close terrain, reduced visibility leaves them vulnerable to dismounted infantry attacks as well. In such situations, they are usually restricted to trails, roads, or streets; this severely limits maneuverability and observation. Existing or reinforcing obstacles can also restrict or stop tank movement.
