From back cover:

“There are two types of cells, sleeper cells and phantom cells. The sleeper cell consists of one lone wolf individual; the phantom cell however is made of no more than 2-5 individuals. Anything beyond 5 members risks falling into the same pitfalls as the organization, and begins to lose its solidity and causes it to be more vulnerable to infiltration, thus compromising its effectiveness. More importantly, cell structure differs from the organization in that, if one cell is taken out and/or compromised, it remains physically impossible for that to have any effect on any other cell. If we drew one big circle or pyramid (the organization), imagine if it only took one pin to stick into the organization block to destroy it. In the case of cell structure, the only way to destroy the cells would be to pin them each one by one, which means you would need to first locate and identify each and every one, and pick them off individually. The chance of successfully identifying all of those unknown numbers of underground cells is usually quite small. This is what gives cell structured resistance its near invincibility.”
