SECTION I.
INTRODUCTION
1-1.
PURPOSE
a.
This Technical Manual (TM) is for use by operators, unit, and direct support maintenance personnel.
It
provides procedures and guidelines for battlefield repairs on the M109A6 howitzer under the forward support maintenance
concept during combat.
b.
The purpose of Battlefield Damage Assessment and Repair (BDAR) is to rapidly return disabled combat
equipment to the operational commander by expediently repairing, bypassing, or jury-rigging components to restore the
minimum essential systems required for the support of a combat mission or to enable the howitzer to self-recover.
These
repairs are temporary, and may not restore full performance capability, and must be replaced with standard repairs at the
first opportunity.
For further Information on doctrine and guidance, see FM 20-30.
1-2.
SCOPE
a.
This TM describes BDAR procedures applicable specifically to M109A6 howitzers.
For further information on
expedient repairs of a general nature applicable to systems or subsystems common to more than one combat vehicle, see
TM 9-2350-276-BD.
b.
Many repair techniques helpful in preparing a howitzer 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.
For further
information on recovery-associated expedient repairs, see FM 20-22.
c.
All possible types of combat damage and failure modes cannot be predicted, nor are all effective field repairs
known.
This TM provides guidelines for assessing and repairing battlefield failures of the M109A6 howitzer and is not
intended to be a complete catalog of all possible emergency repairs.
The repairs described here serve as a guideline and
are intended to stimulate the experienced mechanic to devise methods, as needed, to rapidly repair equipment in a
combat crisis.
d.
Use this TM in conjunction with the M109A6 howitzer system TM’s (TM 9-2350-314 series) and Lubrication
Order (LO 9-2350314-12).
A complete listing of TMs is contained in Appendix A.
1-3.
APPLICATIONS
a.
The procedures in this manual are designed for battlefield environments and should be used in situations
where standard maintenance procedures are impractical.
These procedures are not meant to replace standard
maintenance practices, but rather to supplement them in a battlefield environment.
Standard maintenance procedures will
provide the most effective means to return a damaged vehicle to ready status, provided that adequate time, replacement
parts, and necessary tools are available BDAR procedures are only authorized for use in an emergency situation in a
battlefield environment or in training, and only at the direction of the commander.
