TM 9-2350-274-BD CHAPTER 1 INTRODUCTION BDAR FIXES SHALL BE USED ONLY IN COMBAT AT THE DISCRETION OF THE COMMANDER AND SHALL BE REPAIRED BY STANDARD MAINTENANCE PROCEDURES AS SOON AS PRACTICABLE AFTER THE MISSION IS COMPLETED. SECTION I. General 1-1. Purpose. a. This technical manual (TM) is for use by operators, organizational, and direct support/general maintenance personnel. It provides procedures and guidelines for battlefield repairs on the M 109 Self-Propelled Howitzer/M 110 series Self-Propelled Howitzer/M578 Recovery Vehicle, Full-Tracked, under the forward support maintenance concept during combat. b. The purpose of Battlefield Damage Assessment and Repair (BDAR) is to rapidly return disabled combat vehicles to the operational commander by expediently fining, by-passing, or jury-rigging compo- nents to restore the minimum essential systems required for the support of the specific combat mission or to enable the vehicle to self-recover. These repairs may be temporary and may not restore full performance capability. 1-2. scope. a. This TM describes BDAR procedures applicable specifically to the M 109 vehicles/M110 series vehicles/M578 Recovery Vehicles. Expedient repairs of a general nature applicable to systems or subsystems common to more than one combat vehicle are covered in TM 9-2350-276-BD. b. Many expedient repair techniques helpful in preparing a vehicle for recovery are included in FM 20-22 Vehicle Recovery Operations. Details of such procedures are not duplicated in this TM, although certain quick fix battlefield operations which would, in some cases, prepare the vehicle for recovery or self- recovery will be described. Users of this manual should refer to FM 20-22 for further recovery-associated expedient repairs. c. All possible types of combat damage and failure modes can not be predicted nor are all effective field expedient repairs known. This TM provides guidelines for assessing and repairing battlefield failures of the M 109 vehicles/M110 series vehicles/M578 Recovery Vehicles and is not intended to be a complete catalog of all possible emergency repairs. The repairs described here will serve as guidelines and will stimulate the experienced operator or mechanic to devise expedients as needed to rapidly repair equipment in a combat crisis. Change 1 1-1
