Like how Afghanistan and Yemen and Russia quickly folded to the overwhelming superiority of Western forces?I think however in modern warfare, unless you are resorting to guerilla tactics, once the main support is taken you will lose very fast regardless of will to fight. Modern technology, information and strategy means the enemy knows exactly where to cut you off before you can even react. Before you can regroup together and share willpower together, the enemy would have found ways to prevent that happening and maybe hit you.
Oh wait
