include two Brigade Combat Teams (BCTs), life support capabilities needed to be expanded to accommodate the increased troop presence. As such, half of the company began construction to expand Bagram Airfield before moving to FOB Fenty in February 2007 to rapidly expand housing and infrastructure. The other half of the company was tasked with the same mission at FOB Salerno before the company reconsolidated at FOB Fenty in June 2007. When 173d Airborne Brigade Combat Team took over the battlespace, 76th continued their work, constructing 185 B-huts, four SEA-huts, and six brick-and-mortar barracks across 14 FOBs. The company was then tasked with the winterization of the theater, constructing or upgrading infrastructure at 16 FOBs simultaneously. The company returned to Fort Knox in March 2008. On April 28, 2009, the battalion returned to Afghanistan with 15th Engineer Company, 60th Engineer Company, 76th Engineer Company, and eventually 502d Multi-role Bridge Company, setting up its battalion command post at Kandahar Air Field. With Kandahar as the main hub, the battalion pushed companies to FOBs Wolverine, Frontenac, and Spin Buldak, respectively. Though deployed independently of each other, the three engineer companies had similar missions: expanding life support areas and improving FOB security and force protection measures throughout their AOs. These improvements included helipads, taxiways, UAV landing strips, berms, entry control points, and ammunition holding areas among other construction projects. In total, the battalion completed more than $23 million worth of work while deployed. In August 2009, 502 MRBC joined the battalion in Afghanistan to conduct fixed and float bridging operations throughout Afghanistan. Most of the company, including the headquarters, was stationed at Camp Leatherneck to support operations in the Helmand river valley, while one platoon remained at Kandahar. These elements provided bridge site reconnaissance and support to their respective AOs. Sites included the Saracha Bridge along Highway 1, the Regak Bridge in Uruzgan Province, and the construction of a Mabey Johnson Bridge at the Andar Bridge site. In April 2010, the 19th Engineer Battalion began its return to Fort Knox. In Nov 2013, 19th Engineer Battalion, along with 450 Soldiers, deployed to Kuwait on their fourth deployment since their reactivation at Fort Knox under the command of LTC John Lloyd. During the deployment, the unit was responsible for road construction, infrastructure improvements, and a variety of facility upgrades, including projects in Tajikistan. The unit redeployed to Kentucky in August 2014. In Mar 2016, 42nd
