Resistance movements can include any irregular armed force that rises up against an enforced or established authority, government, or administration. This frequently includes groups that consider themselves to be resisting tyranny. Some resistance movements are underground organizations engaged in a struggle for national liberation in a country under military occupation or totalitarian domination.
Tactics of resistance movements against a constituted authority range from nonviolent resistance and civil disobedience, to industrial sabotage and guerrilla warfare, or even conventional warfare if the resistance movement is strong enough. Any government facing violent acts from a resistance movement usually condemns such acts as terrorism, even when such attacks target only the military or security forces.

Resistance during World War II was dedicated to fighting the Axis invaders. Germany itself also had an anti-Nazi German resistance movement in this period. Although mainland Britain did not suffer invasion in World War II, the British made preparations for a British resistance movement in the event of a German invasion.
US government definition:

According to Joint Publication 1-02, The United States Department of Defense defines a resistance movement as: An organized effort by some portion of the civil population of a country to resist the legally established government or an occupying power and to disrupt civil order and stability.

In strict military terminology, a resistance movement is simply that; it seeks to resist (change) the policies of a government or occupying power. This may be accomplished though violent or non-violent means. A resistance movement is specifically limited to changing the nature of current power, not to overthrow it. The correct military term for removing or overthrowing a government is an insurgency.
