It is interesting to compare Marine preparations to assault Fallujah in April 2004 with those apparently under way today, just months later. The Marine methods of April would have been instantly familiar to any military historian: hammer and anvil, seizure of key terrain; feint and attack. Today, many of the military objectives in the developing siege of the terrorist stronghold are abstract. They consist of developing a network of informers in the city; of setting up a functioning wireless network; of getting close enough for smaller US units to deploy their line-of-sight controlled UAV and UGV units to create a seamless operational and tactical environment to wage "swarm" warfare; of getting artillery and mortar units close enough to play hopscotch over everything the network decides to engage. To the traditional methods of warfare the Americans were adding a whole new plane which only they could inhabit.
It looks like large organizations can adopt strategies to beat a small, dispersed, loosely connected foe. Thank goodness the leadership had the willingness to let go of traditional tactics and lear new ones on-the-fly.
