A guerrilla warfare is a paramilitary group used during combat, to fight a larger military group. The use of guerrilla warfare during wartime includes ambushes, sabotage, and even raids. These groups are similar to the flexible response in the sense that they are both military strategy. Flexible response was first used by US President John F. Kennedy as a military strategy during the cold war and it refers to the status quo of heavily armed war not limited to nuclear arms. In simple terms, Flexible Response is the capability to annihilate your enemy as it destroys you completely, calling for the prevention of attacks. Even though both terms represent strategic approaches to war, they wage different results. In a sentence, guerrilla warfare leverages power of military groups without compromising the whole power of the army, while flexible response uses the whole power of an army to wage on stability and status quo.
