Where the operations are defensive in character any special movement or movements may be offensive.
OBJECTIVE
Objective
An objective is "any point or force against which an offensive movement is directed." Thus where the object in any theatre of operation is to get command of a certain sea in which the enemy maintains a fleet, that fleet will usually be the objective.
LINES OF OPERATION
Lines of operation.
A line of operation is "the area of land or sea through which we operate from our base or starting point to reach our objectives."
Lines of operation may be exterior or interior. We are said to hold the interior lines when we hold such a
position, in regard to a theatre of operations, that we can reach its chief objective points, or forces, more quickly than the enemy can move to their defence or assistance. Such a position is called an interior position. "Exterior Lines" and "Exterior Position" are the converse of these.
