US Marines from the 2nd Battalion, 8th Marine Regiment of the 2nd Marine Expeditionary Brigade walk towards the helicopter as part of Operation Khanjar at Camp Dwyer in Helmand Province in Afghanistan on July 2, 2009. US Marines launched a major offensive into the Taliban heartlands of southern Afghanistan before dawn as President Barack Obama’s new war plan swung into action. With dozens of aircraft ferrying out troops from various bases, the assault aimed to insert forces into insurgent strongholds in Helmand province in what officers said was the biggest offensive airlift by the Marines since Vietnam. Operation Khanjar (Strike of the Sword), involving nearly 4,000 US forces as well as 650 Afghan police and soldiers, would bring security to the Helmand River valley ahead of presidential elections on August 20, commanders aid.
