Stretched by frequent troop rotations to Iraq and Afghanistan, the Army has become a “thin green line” that could snap unless relief comes soon, according to a study for the Pentagon.
Andrew Krepinevich, a retired Army officer who wrote the report under a Pentagon contract, concluded that the Army cannot sustain the pace of troop deployments to Iraq long enough to break the back of the insurgency.
