The brigade was formed on 27 June 2018 inTernopil Oblast.[2] On 2 August inBorshchiv, over 200 reservists were gathered for training.[3][4] In November a recruitment drive was organized to fill the brigade's ranks.[1] In February[5] and March[6] 2019 the brigade held readiness exercises.
On 4 March,Ternopil Oblast governorVolodymyr Trush announced that the brigade was at its full strength. Its soldiers were tasked with defense of critical infrastructure, manning roadblocks and helping postal workers deliver pensions.[7][8]
In early March 2022, the 105th Brigade was ordered to form a consolidated battalion to be deployed into combat operations. It was initially planned that one company would be sent from each of the brigade's 80th, 82nd, 83rd, and 85th Battalions. Units of the 105th Brigade's consolidated battalion began deploying by 11 March.[8]
In mid-March, the 105th Brigade's consolidated battalion was positioned on the border between thePoltava Oblast and theSumy Oblast in order to repel a potential Russian offensive in the area ofRomny. The battalion manned checkpoints, guarded bridges, and patrolled villages, but did not engage in combat with Russian forces. By the end of April, units of this battalion were redeployed toUdy in theKharkiv Oblast in order to repel a potential Russian offensive from the village ofKozacha Lopan. In mid-May, the consolidated battalion was disbanded, and its constituent units were returned to the territorial defense battalions from which they had been taken.[8]
In April 2022, units of the 105th Brigade were deployed to the combat zone in theKharkiv Oblast,[9] including nearBarvinkove.[10][11] Starting on 15 April, the brigade's 83rd Battalion held a 20 kilometres (12 mi) defensive line from the western outskirts of Barvinkove to the villages ofChervona Zoria [uk] andSemenivka [uk], with its command post in the village ofAfrykanivka [uk].[8]
At the end of June 2022, the brigade's 83rd Battalion was subordinated to the95th Air Assault Brigade, and was deployed to a defensive line in theDonetsk Oblast passing through the villages ofMazanivka [uk],Krasnopillia [uk] andDolyna [uk]; its command headquarters were in the village ofNovomykolaiivka.[8]
In late August and early September 2022, the 83rd Battalion advanced 10 kilometers from its positions on this defensive line in the direction ofIzium, as part ofa major Ukrainian offensive.[8] It has been reported that the brigade's 83rd Battalion operated in the villages ofVelyka Komyshuvakha,Topolske [uk], andKam'yanka [uk].[9]
During the same offensive, on 9 September, the brigade's 80th Battalion, under the command of theLyman operational-tactical group [uk], was assigned to take part in an operation to capture the villages ofBilohorivka in theLuhansk Oblast andSpirne in theDonetsk Oblast, in order to improve the tactical situation on theSiversk front, prevent future Russian offensives onSloviansk andKramatorsk, and create conditions for a Ukrainian offensive onLysychansk. In cooperation with the54th Mechanized Brigade, a unit of the 80th Battalion retook the village of Spirne.[12]
