air battle management

a fundamental task of air defense

command and control and airspace management which

encompasses the principles for the control and

coordination of both tactical air and ground-based

air defense resources. Air battle management is

exercised through positive and procedural

methods.

riendly aircraft and established for the purpose of

preventing friendly aircraft from being fired upon

by friendly forces.

effectiveness of attack by hostile aircraft or guided

missiles both before and after they are airborne.

including guns and surface-to-air missiles and

support equipment, for engaging air targets.

and control thereover as he does over units and

persons organic to his command. However, the

responsibility for transfer and promotion of

personnel will normally be retained by the parent

formation, unit, or organization.

attack

an offensive action characterized by fire and

maneuver and culminating in a violent assault or, in

an attack by fire, in the delivery of intensive direct

and trailing element are separated by a short

distance which varies with the terrain. The trailing

element moves at variable speeds and may pause

for short periods to overwatch the lead element. It

keys its movement to terrain and the lead element.

It overwatches at a distance such that enemy

engagement of the lead element will not prevent

the trailing element from firing or moving to
