MARITIME DOCTRINE OF SRI LANKA
Compellance

Achieving the change of behaviour of enemy by inducement using own
military force and its capabilities is termed as compellance. In order to
induce the enemy’s behaviours, a superior force is requested with better
communication and correct leadership to control the enemy’s use of
force. 27

“The skilful commander imposes his will on the enemy
by making the enemy come to him instead of being
brought to the enemy.”

Sun Tzu

Coercion

The use of own military capabilities as threat against the enemy to
hinder their will to fight and achieve superiority over them is termed as
coercion. In this context, psychological pressure build up on the enemy
is more appropriate than the physical pressure imposed on them.
Thereby, own forces will be able to destroy enemy’s will to continue the
aggression. 28

“The supreme art of war is to subdue the enemy without
fighting.”

Sun Tzu

Deterrence

Deterrence is preventing aggression by convincing a potential aggressor
that the cost of coercion would be more than its likely gain. This could
be achieved by raising the cost (deterrence by punishment) or denying
the gains (deterrence by denial). Similarly, deterrence could be define
as passive deterrence which is implicit in the maintenance of military
capability, strategy and active deterrence requires a more overt posture
in terms of deployment and readiness. 29
