Five years after the U.S.-led invasion of Iraq , the military is being reconfigured to fight insurgencies, but its evolution has been an unplanned, improvised affair, a series of course corrections in the midst of the wars in Iraq and Afghanistan . Some changes have been simply last-ditch efforts to stop the violence against Iraqis and U.S. troops, and some say the changes impair the military's ability to fight a conventional war against a "peer competitor."

Divisions are dispersed into what the military calls a more modular Army so smaller units can be moved throughout Iraq . The military has rolled out new vehicles to thwart high-powered explosives. It's set up new training centers and given captains and colonels far more leeway to lead at the local level, not simply follow a general's orders.

Pentagon leaders call this the military of the future.

"Clearly the training now is almost exclusively focused on COIN (counterinsurgency) because that's the fight we are in. And it will continue that way as long as the fight stays at the level that it is," said Adm. Michael Mullen , chairman of the Joint Chiefs of Staff, in an interview with McClatchy .
