Which has both it advantages and disadvantages. The most obvious disadvantage is that they can't coordinate forces to launch coordinated actions on large scale. The advantage is that counterinsurgency can't decapitate them by killing couple of people and thus remove entire leadership nor can it infiltrate them all to same level. If you destroy one group there are many more that are still up and running.

Afghan muyahedeen had similar "structure".
