Security is a condition that gives a commander sufficient freedom of action to fulfil his aim. Security is manifested in the offence by having a firm base for the assembly, preparation and launching of operations. It includes securing the line of departure (LD), the flanks of an attacking force, and the lines of communications (LOC). During counter-insurgency (COIN) operations and certain peace support operations, forces will require a secure base from which to operate. Once the desired effects have been created in these base areas, the campaign can be extended, like oil spreading in water, to less secure areas.
