Today, half of Baghdad is now secured. In April, 19% of the city was under secure control. In June, 40%.

Pattern analysis tells us about the war’s progress. Insurgent controlled zones are “Red,” contested zones are “Purple,” and secured zones are “Blue.” Baghdad is now 48% Blue, 36% Purple and 16% Red. Red continues to recede.

Bill Roggio describes the order of battle with a map here.

Baghdad is divided into 474 neighborhoods. Coalition Forces use different strategies to approach each neighborhood.

Disruption – In Insurgent controlled zones, raid and disrupt their organization and operations and collect intelligence.
Clearance – Where Insurgents are weakened, heavy raiding and patrolling contests the zone and expells insurgents.
Controlling – Consolidating and holding territory. This is the highest level of security.

Controlled areas can be turned over to the Iraqi Government.

Maj Gen Fil compared the numbers from April to today. In April about 19 percent of Baghdad was secured, 41 percent of Baghdad was yet to be cleared, and about 35 percent of Baghdad was in the process of being cleared. In May, as The New York Times reported, the number of neighborhoods under control jumped to 29 percent, but there was no discussion of neighborhoods in the clearance and disruption phases.

The numbers have changed dramatically in the two months since April. Today about 48 percent of Baghdad is secured, with 7 percent under the control of the Iraqi security forces in the retain phase, 16 percent of Baghdad has yet to be cleared, and about 36 percent of Baghdad is in the process of being cleared.

Clearing Baghdad involves other battlefields. Coalition Forces are engaging the enemy in the “belts” around Baghdad in the Diyala, Anbar, and Babil provinces.

We have to attack and disrupt enemy operations and prevent regeneration. This offensive attacks car bomb factories and insurgent bases. This disrupts their ability to move fresh men and material into Baghdad to carry out terrorist attacks or reinforce insurgent zones.
