APPLICATIONS - CONTINUED
b.
BDAR techniques are not limited to simple restoration of minimum functional combat capability.
If full
functional capability can be restored expediently with a limited expenditure of time and assets, this should be done.
c.
Some of the special techniques in this manual, if applied, may result in shortened life or damage to
components of the M109A6 howitzers.
The commander must decide whether the risk of having one less howitzer
available for combat outweighs the risk of applying the potentially destructive repair technique.
Each technique gives
appropriate warnings and cautions, and lists system limitations caused by this action.

DEFINITIONS
a.
Battlefield Damage (BD) includes all incidents which occur on the battlefield and which prevent the vehicle
from accomplishing its mission, such as combat damage, random failures, operator errors, accidents, and wear-out
failures.
b.
Battlefield Damage Assessment (BDA) is a procedure to rapidly determine what is damaged, whether it is
repairable, what assets are required to make the repair, who can do the repair, and where the repair should be made.
The
assessment procedure includes the following steps:
(1)
Determine if the repair can be deferred, or if it must be done at once.
(2)
Isolate the damaged areas and components.
(3)
Determine which components must be fixed.
(4)
Prescribe fixes.
(5)
Determine if parts of components, materials, and tools are available.
(6)
Estimate the manpower and skill required.
(7)
Estimate the total time (clock-hours) required to make the repair.
(8)
Establish the priority of the fixes.
(9)
Decide where the fix shall be performed.
(10) Decide if recovery is necessary and to what location.
c.
Battlefield Damage Repair (BDR) in this manual includes any expedient action that returns a damaged part or
assembly to a full or an acceptably degraded operating condition, including:
(1)
Short cuts in parts removal or installation.
(2)
Installation of components from other vehicles that can be modified to fit or interchange with
components on the M109A6 howitzer.
(3)
Repair using M109A6 howitzer parts that serve a non-critical function elsewhere on the same howitzer
for the purpose of restoring a critical function.
(4)
Bypassing of non-critical components in order to restore basic functional capability.
(5)
Expeditious cannibalization procedures.
(6)
Fabrication of parts from kits or readily available materials.
(7)
Jury-rigging.
(8)
Use of substitute fuels, fluids, or lubricants.
