After World War I , the battalion was declared inactive except for A Company , which was transferred to Fort Riley , Kansas to provide engineer support to the Cavalry School . From 1923 to 1936 , A Company provided vital training and infrastructure support to the Cavalry School first as a unit of the 2nd Cavalry Division and later as Troop A , 9th Engineer Squadron . The performance of Troop A during this period established a tradition of excellence for the 9th Engineer Squadron as a mounted cavalry unit . The platoon leader during a significant portion of that period was 1LT Samuel D . Sturgis , Jr . , later to become the Chief of Engineers as a Lieutenant General . World War II . Following the outbreak of World War II , the battalion was activated as the 9th Armored Engineer Battalion , part of the newly 9th Armored Division .

Pepper Bypass at Omerbegovaca . The battalion was replaced by elements of the 82nd Airborne Division and returned to Schweinfurt in April 1997 . For its actions in Bosnia , the battalion was awarded the Army Superior Unit Award . The 9th Engineer Battalion was deployed to the Balkans as part of Kosovo Force ( KFOR ) during Operation Joint Guardian II in June 1999 under Task Force Falcon . It was the first U .

On 1 January 2009 Soldiers in Iraq started operating under new rules in compliance with the newly minted U . S . – Iraq Status of Forces Agreement . The most significant policy shift affected troops on the ground by putting Iraqi forces in the operational lead in most areas . Under the agreement , TF Gila Route Clearance Packages only operated during daylight hours partnered with Iraqi forces , and could only conduct unilateral operations at night . Before redeploying , Iraqi Route Clearance Units led TF Gila units on partnered missions . Gila Battalion supported the Iraqi Police ( IP ) and Iraqi Army ( IA ) as they secured voting sites and ballots for the 2009 local elections .

No element following a Bravo Co route clearance patrol was ever struck by an IED . On 4 May , Bravo Co successfully launched four mine - clearing line charges ( MICLIC s ) to breach RTE Headhunters , a heavily mined route , detonating at least 4 IEDs and multiple anti - tank mines during the initial breach . In doing so , the company became one of only a handful of engineer companies to conduct the task in a combat environment since the start of war in Iraq . Bravo Co provided general engineering support to the task force . The company oversaw the construction of several COPs which included the addition of T - Walls , urine soak pits , burn latrines , and personal hygiene stands . The Society of American Military Engineers awarded Bravo Company the 2009 Itschner Award . The Itschner Award is named in honor of Army Lt . Gen . Emerson C . Itschner .

The Headquarters and Headquarters Company ( HHC ) of the 9th Engineers operated out of Forward Operating Base Rushmore ( Sharan District , Paktika Province ) . In addition to providing Command and Control of TF Gila , HHC conducted training and partnership operations with the Afghan Uniformed Police ( AUP ) and the Afghan Local Police ( ALP ) in Paktika . HHC was augmented by a platoon from the 554th Military Police Company who were the main effort in the training of AUP and ALP throughout the province . HHC ' s Support Platoon also conducted partnered patrols throughout the province in order to allow key leaders of the AUP as well as TF Gila to conduct battlefield circulation to outlying AUP checkpoints . Alpha Company , 9th Engineers served as a route clearance and route improvement Company based at Forward Operating Base Sharana ( Sharan District , Paktika Province ) . The Company ' s two route clearance platoons ( coded RCP 5 and RCP 6 ) helped maintain freedom of maneuver throughout Paktika province and as far north as Ghazni City and operated extensively with the Afghan RCC ( Route Clearance Company ) from 2nd Brigade , 203 Corps , who took complete responsibility for device detection and clearance by the end of the deployment . Notable achievements included arriving by land to COP Curry , COP Tillman and COP Waza Khwa for the first time in over a year . The RCP platoons also performed construction security , logistical support , and traffic control point missions routinely . The company had a construction section that partnered extensively with Afghan engineers to accomplish road improvement , culvert repair , and facilities construction . They were known for their ability to move a small team to a remote COP by helicopter , repair significant structural damage to buildings using only materials at hand , and leave within two weeks . Two additional platoons from Alpha were detached to assist with the handover of COP Waza Kwah in southwest Paktika to Afghan National Security Forces ( ANSF ) . Following the handover , those two Platoons augmented Able and Venom Companies of TF Black Scarves ( 1st Battalion , 2nd Infantry Regiment ) in Andar , Ghazni with the mission to fight as Infantry . Bravo Company , 9th Engineers , fell under the 2nd Battalion , 28th Infantry Regiment , operating out of Combat Outpost Curry ( Gomal District , Paktika Province ) with the mission to fight as Infantry . While stationed in Gomal , Bravo Company worked with ANSF to increase security , governance , economy , and partnership in the district . ANSF partnership was the primary mission for Bravo Company , and they worked daily with the Afghan National Army ( ANA ) , Afghan Border Police ( ABP ) , and Afghan National Police ( ANP ) . The Sappers went on security patrols throughout Gomal District , both mounted and dismounted . Despite rugged terrain , the ANSF and Bravo Company successfully patrolled throughout the largest district in Paktika Province . Bravo leaders and Soldiers trained ANSF Soldiers and Policemen to enhance their capabilities , allowing ANSF to conduct unilateral patrols by the spring of 2012 . Because of COP Curry ' s remote location in Paktika , resupply was accomplished via the Air Force ' s Air Delivery Systems ( ADS ) . Bravo regularly received food , water , fuel , and ammunition via air drop . During the deployment , they also received the largest air drop to date in operation Enduring Freedom , accepting a 4K all - terrain forklift . Charlie Company served under several successive Task Forces from 2011 to 2012 : TF Warrior , TF Thunder , TF Gunner , and TF Black Scarves . Charlie operated out of COP Sayed Abad ( Sayed Abad District , Wardak Province ) , COP Dashe Towpe ( Chak District , Wardak Province ) , and COP Band E Sardeh ( Andar District , Ghazni Province ) with the mission to fight as Infantry . In Wardak , Charlie Company augmented an Afghan Army Kandak and TF Warrior in a clear - hold - build operation to secure the Chak District Center .

In December 2011 , Charlie moved to COP Band E Sardeh in Andar District , Ghazni to replace Alpha Company , 2nd Battalion , 2nd Infantry Regiment , 1st Infantry Division . Co - located with an Afghan Army Kandak , Charlie conducted partnered counterinsurgency operations in Andar , Dih Yak , and Giro Districts . Charlie ' s counterinsurgency efforts , empowering local leaders , and strengthening the local Afghan Army were likely instrumental in the " Andar Uprising " against the Taliban in the summer of 2012 , beginning just as Charlie was redeploying . TF Gila redeployed to Germany in June 2012 and inactivated on 31 May 2013 . Lineage .
