Following this, A/1-17 IN and B/4-23 IN pushed west into northern Marjeh to conduct disruption operations, while the Reconnaissance Platoon conducted screening along the northern corridor in order to prevent the infiltration of Taliban reinforcements. Task Force Mohawk continued operations until 6 March, when they were relieved by elements of 3/6 Marines. In the month long operation, the task force had 15 enemy KIA, 9 enemy WIA, 23 IEDs found and cleared, 8 IED strikes, and 497 individuals enrolled in biometric systems. 4-23 IN and its supporting elements were recommended by Task Force Leatherneck for a Presidential Unit Citation for their actions in Marjeh. During February, several smaller company operations were conducted along HWY 601 and in the Yakhchal valley. Company A conducted Operation '601 Cougar', clearing north through Gavban in the southern Yakhchal, which yielded a great amount of intelligence about the enemy in the area. Company C conducted missions in Mohammad Karim Kalay, as well as Yakhchal, in order to disrupt enemy forces influencing HWY 1. Throughout the remainder of the deployment, 4-23 IN continued to provide freedom of movement along the highways, while simultaneously planning to hand over their vehicles and equipment to the 2nd Stryker Cavalry Regiment and hand over the Helmand battlespace to the 2nd Marine Expeditionary Brigade and the Danish battlegroup. The final battalion operation was the move back to Zabul Province in order to set up operations for the 2nd Stryker Cavalry Regiment to assume responsibility.  4-23 IN returned to Fort Lewis in July 2010 following its 12-month deployment. The battalion was part of the first Stryker unit to deploy to Afghanistan. 4-23 IN was the only Stryker battalion operating in the remote, mountainous terrain of Zabul Province, which required greater logistical coordination, maintenance, and care of equipment than any other unit. The battalion was the only infantry unit in Afghanistan to be tasked to move across two provinces and set up operations in an entirely new area. 4-23 IN was the only U.S. Army unit to take part in Operation 'Moshtarak', the largest offensive operation in Afghanistan since the war began in 2001. 4-23 IN was also the only U.S. Army Infantry battalion operating in the volatile Helmand Province. 4-23 IN as part of 5th Stryker Brigade, 2nd Infantry Division was the second U.S. Army brigade to deploy with the Landwarrior system.  4-23 IN deployed in April 2012 under the reflagged 2nd Stryker Brigade, known as the Lancers, 2nd Infantry Division to the Maiwand and Zharai District and returned to Joint Base Lewis-McChord in January 2013.  1-23 IN deployed in March 2012, 3rd Stryker brigade combat team, to Panjwai district, Kandahar province, Afghanistan.
