PURPOSE AND SCOPE 1. Purpose This manual provides information and guidance on doctrine, tac- tics, and .techniques for the employment of platoon-, company-, and battalion-size armor units (hereafter referred to as small armor ?units). It should be used in conjunction with appropriate field man- uals of the 17 and other series. It provides the basic doctrine, tactics, techniques, and procedures common to two or more types of small armor units. Other publications provide the specific doctrine, tactics, techniques, and procedures for specific units. In addition, this manual supplements the doctrine stated in FM 100-5 and the staff procedures contained in FM 101-5. 2. Scope a. This manual covers basic doctrine, tactics, and techniques of employment; organization; exercise of command; reconnaissance; se- curity; administration and logistics; control; movements; and offen- sive, defensive, retrograde, and special operations appropriate to all small armor units. This general information is not repeated in other armor unit manuals. This manual duplicates other field manuals only where necessary to ensure clarity and understanding. Unless other- wise specified, the material presented herein is applicable without modification to both atomic and nonatomic warfare. b. Small armor units include platoon-, company-, and battalion-size units of tanks, armored infantry, and armored cavalry, within the armored division, infantry division, airborne division, armored cav- alry regiment, and other corps and army organizations. These are referred to generally, in this and other 17-series field manuals, as armor units. Currently prescribed terminology for these units differs in several respects from that heretofore used; the following are cur- rent titles and designations of armor units in divisions. Title* Designlation* Armored infantry battalion_________- _ Armored Rifle Battalion, Infantry. Rifle company, armored infantry bat- Co - , Armored Rifle Battal- talion. ion, Infantry. *The title is used when making a general reference to the type unit; the designation is used in referring to a specific unit. 3 Title* Designation* Armored division armor battalion, 90- __ Medium Tank Battalion (Pat- mm. ton), Armor. Medium tank company, armored divi- Co _ , __ Medium Tank Bat- sion armor battalion, 90-innm. talion (Patton), ._ Armor. Armored cavalry squadron____________ lReconnaissance Squadron, Calvary. Reconnaissance troop, armored cav- Troop, - , -- Reconnaissance alry squadron. Squadron, - Cavalry. Infantry division armor battalion, 90- -- Medium Tank Battalion (Pat- lnm. ton), _ Armor. Medium tank company, infantry divi- Co , Medium Tank Bat- sion armor battalion, 90-mm. talion (Patton), Armor. Infantry division cavalry squadron____ Reconnaissance Squadron, Cavalry. Reconnaissance troop, infantry divi- Troop , __ Reconnaissance sion cavalry squadron. Squadron, - Cavalry. Airborne division cavalry troop_______ Troop (Reconnaissance) (Air- borne), Cavalry. *The title is used when making a general reference to the type unit; the designation is used in referring to a specific unit. Throughout this manual, where the word battalion appears in a gen- eral sense (battalion commander, battalion staff, battalion trains), it is to be considered as applying equally to the armored cavalry or infantry division cavalry squadron. Likewise, a general reference to company applies equally to the reconnaissance troop. Section II. THE ROLE OF ARMOR 3. General Technological developments and doctrinal and organizational con- cepts indicate that increased emphasis will be placed on combat opera- tions that are characterized by open and fluid warfare, with greater dispersion of tactical formations and installations. The decisive elec- ment of these operations will be the rapid concentration of the combat power required to achieve a tactical advantage. Upon the accomplish- ment of a mission, immediate dispersion of this combat power will be necessary to avoid enemy atomic retaliation. Armor is designed for the conduct of mounted mobile warfare. Its capabilities have assumed increased importance within the role that ground forces will play on the battlefield. 4. Definition of Armor The term armor embraces the tank, armored calvary type recon- naissance and security elements, armored infantry, artillery, engineer, and mobile service support units required to form an integrated and balanced fighting force for the conduct of mounted warfare, the nu- cleus of which is tanks. The term armor as used in this and 17-series manuals should be so interpreted. It should
