A US ARMY BASE, Kuwait (AFP) – The US army has nearly completed the largest logistics operation since World War II in pulling thousands of combat troops and more than one million pieces of equipment out of Iraq, a senior officer says.

“Its the largest drawdown since World War II,” Colonel Donnei Walker, commander of the First Sustainment Brigade, US Third Army, said at a key US military facility in Kuwait through which most of the equipment has passed.

“We have moved out nearly 1.2 million pieces of equipment,” since the operation began more than a year ago, Walker told reporters during a tour of the facility in southern Kuwait on Friday.

The base’s name was withheld for security reasons.

Walker, whose brigade is responsible for transporting materiel, was inspecting a new transportation convoy that was preparing to leave for Iraq to pick up a new shipment.

The pullout is scheduled to be completed before the end of the month.

Each convoy normally consists of 40 vehicles of heavy equipment transporters, well-fortified large trucks and several armoured vehicles that provide protection.

The equipment included thousands of tanks, different kinds of other military vehicles, repair parts and general supplies.

The brigade is part of the First Theatre Sustainment Command (TSC), Third Army, which has been responsible for the massive logistics operations for the wars in Iraq and Afghanistan.

At another location on the massive base, a second convoy of truck transporters carrying Mine Resistant Ambush Protected (MRAP) vehicles was just arriving from Iraq.

The large trucks lined in an orderly manner and workers immediately began off-loading the MRAPs.

Thousands of tanks and heavy military vehicles, known by officers as pre-positioned equipment, filled a large space on the facility.

The equipment is properly checked and then washed before being shipped, either back to the United States, or to Afghanistan or one of the 16 countries where the Third Army operates.

During the operation “about 1,500 long-haul trucks were going to Iraq daily to load stuff,” the deputy commander of First TSC in Kuwait, Brigadier General Nick Tooliatos, told reporters.

Part of the equipment had been shipped to Afghanistan, but now “the flow of forces and equipment to Afghanistan (from Iraq via Kuwait) is almost finished,” and almost everything goes back to the United States, he said.

The operation included moving close to 3,000 tonnes of ammunition from Iraq to Afghanistan.

Colonel Gerald O’Hara, Third Army public affairs chief, said more than 90,000 US combat troops had been pulled out during the operation that began in June 2009 and accelerated to full speed just a few weeks after the March 7 Iraqi general elections.

On Thursday, the United States pulled out the last combat brigade, the 4th Stryker Brigade, 2nd Infantry Division, into Kuwait and reduced its troops to just 52,000.

The strength of US troops in Iraq is set to drop to 50,000 by September 1, less than a third of the peak level during the 2007 “surge.”

From next month the US mission in Iraq will be called “Operation New Dawn” instead of “Operation Iraqi Freedom” — the name given to American operations since the invasion.

“Most of the troops withdrawn from Iraq passed through Kuwait on their way back home,” O’Hara told AFP.

Currently, there are between 15,000 and 20,000 US troops in the oil-rich emirate, which served as the launch pad for the March 2003 US-led invasion of Iraq that toppled Saddam Hussein, he said.

The forces are present at Camp Arifjan, the main US army base 70 kilometres (44 miles) south of Kuwait City, and several other smaller camps in the northern desert close to the Iraqi border.

O’Hara said the number of attacks on US convoys has sharply dropped to “one to two” a week and were not as serious as attacks used to be in Iraq.

“We have not seen much of a threat” from the attacks, said Walker.

Major General Peter Vangjel, Third Army deputy commanding general, said the United States has not yet decided about the future of its military presence in the region following the pullout from Iraq.

He said the US and Kuwaiti governments will discuss the issue of US military presence and the renewal of the defence pact, which runs out in 2012.

“Kuwait has been a great partner … and we look forward to continue our relationship with Kuwait,” said Vangjel.
