Ken,

Good examples. Instead of saying to what 'mass' is only applicable, I should have pointed out where I think it's inapplicable. When conducting a strategy of insurgency, the aim, as I understand it, is to avoid massing (people, effects, etc) in the first place, as it presents oneself as a vulnerable target to a superior enemy. It is not always necessary for the insurgency to mobilize "adequate combat power at a decisive point to achieve temporary superiority" because the physical destruction of the enemy is not the goal. Thoughts?
