Battle Damage
Assessment
(BDA)
The estimate of damage resulting from the application of military force against a
predetermined objective. Battle damage assessments can be applied to the use
of all types of weapons systems throughout the range of military operations.
BDAs are primarily an intelligence responsibility with required inputs and
coordination from the operators. BDA is composed of physical damage
assessment, functional damage assessment, and target system assessment.
Battlefield
Coordination
Element (BCE)
An Army liaison provided by the Army component commander to the Air
Operations Center (AOC) and/or to the component designated by the joint force
commander to plan, coordinate, and de-conflict air operations. The battlefield
coordination element processes Army requests for tactical air support, monitors
and interprets the land battle situation for the AOC, and provides the necessary
interface for exchange of current intelligence and operational data.
Baseline Defined quantity or quality used as starting point for subsequent efforts and
progress measurement. Can be a technical baseline or cost baseline.
Baseline
Comparison
System (BCS)
A current operational system, or a composite of current operational subsystems,
which most closely represents the design, operational, and support
characteristics of the new system under development.
Baseline
Conditions
The natural and human environmental conditions, which are present prior to
implementation of a program and against which impacts are assessed.
Baseline Cost
Estimate (BCE)
A detailed estimate of acquisition and ownership costs normally required for highlevel
decisions. This estimate is performed early in the program and serves as
the base point for all subsequent tracking and auditing purposes.
Base Program The base program is the program described in the Future Years Defense
Program base file, when updated to conform to the budget presented to
Congress in January. It constitutes the base from which all current-year program
changes are considered.
Base Year A reference period, which determines a fixed price level for comparison in
economic escalation calculations and cost estimates. The price level index for
the base year is 1.000.
Battle Debris Battle Debris are the fragments produced by the hypervelocity collision of an
interceptor with a ballistic missile, post-boost vehicle, or reentry vehicle, objects
resulting from intentional fragmentation or accidental detonation of booster
components, and objects normally associated with the deployment and
propagation of threat objects (such as nuts, bolts, inter-stages, fairings, shrouds,
etc.).
Battle Group (1) Domains into which the battle space is partitioned. (2) A data processing
approach implemented in the battle management computer, which
minimizes the processing load by partitioning (grouping) threat data
(Virtual Battle Group). (3) A group of associated system elements which
operate together in a segment of the battle, based upon their
capabilities and relative location to each other and the threat.
Battle Integration Preplanning processes and/or real-time coordination that occur to minimize
resource wastage between battle tiers or battle partitions.

Battle
Management
(BM)
Battle management is comprised of two parts: strategies and the collection of
tasks to be performed to successfully implement chosen strategies. Given a set
of strategies, resources, and hostile asset deployment, battle management
addresses the problem of choosing a specific strategy or set of strategies and
performing the associated tasks, which would result in the most desired outcome.
