The plans for Falluja are that when people return, they will all be bio ID-ed, and they will be forced to wear badges displaying their home addresses at all times:

"Under the plans, troops would funnel Fallujans to so-called citizen processing centers on the outskirts of the city to compile a database of their identities through DNA testing and retina scans. Residents would receive badges displaying their home addresses that they must wear at all times. Buses would ferry them into the city, where cars, the deadliest tool of suicide bombers, would be banned."

Furthermore, men will be forced to work in "military style battalions":

"One idea that has stirred debate among Marine officers would require all men to work, for pay, in military-style battalions. Depending on their skills, they would be assigned jobs in construction, waterworks, or rubble-clearing platoons."
