and economic projects. An empathetic leader, he insisted that his troops re-
spect local customs, ordering them, for instance, to wait at the door of a house
for the man to come out rather than barge in unannounced and needlessly
insult the family’s honor. Petraeus improved the living conditions in prisons,
cracked down on interrogators who beat detainees, and invited Iraqi religious
and civic leaders to see the prisons with their own eyes.26
One of the most important leadership challenges, Petraeus found, was allo-
cating unanticipated leadership tasks to subordinate commanders and sta
ocers. All of his ocers had new duties on top of those for which they had
been trained. e trick was to match tasks to personalities. “One of the jobs of
a leader is to employ everybody in his organization in the best way possible to
get the most out of them, to help them be all they can be,” said Petraeus. “In
other words, the S-3 (operations ocer) must do the S-3 business, but it may
be that [the commander] also can use the S-3 to engage with certain leaders
because he’s really good at it. Or maybe not, maybe the S-5 (civil aairs ocer)
has to do it, or the deputy commander.”27
Most of the U.S. Army commanders knew little about counterinsurgency at
the start of the occupation. ose who were not creative or exible gravitated
toward relatively simple counterinsurgency methods of questionable utility—
brief forays into hostile territory, highly destructive attacks on suspected in-
surgent hideouts, and mass arrests. On the other hand, creative and exible
ocers soon came up with eective methods. To nd methods that might be
worth trying, battalion and company commanders read books and articles on
counterinsurgency, tapped Reservists and National Guardsmen with pertinent
expertise, and sent e-mails to experts back in the United States. Using these
ideas and their own ingenuity and judgment, they produced methods tailored
to local conditions. ey formed city councils, funded small businesses, orga-
nized community policing, repaired damaged infrastructure, and performed
a myriad of other previously unencountered tasks. ey devised innovative
countermeasures whenever the insurgents adopted new IED technologies
and tactics, and they invented schemes for collecting intelligence—disguis-
ing soldiers as water and sewer surveyors, for instance.28 Major General Peter
Chiarelli, who commanded the Army’s 1st Cavalry Division during one of
the rst counterinsurgency campaigns in Baghdad, attributed the division’s
achievements primarily to the ability of small-unit leaders to adapt.29 Petraeus
later observed, “e key to many of our successes in Iraq, in fact, has been
leaders—especially young leaders—who have risen to the occasion and taken
