401st Infantry Battalion

401st Infantry Battalion was a unit of the Ukrainian Ground Forces.

It was formed and assigned to the 143rd Mechanized Brigade in 2023 as a Reserve Rifle Battalion, before being reformed as the 401st Infantry Battalion.

In 2024, the battalion became defunct and was reformed as the 2nd Rifle Battalion of the 110th Mechanized Brigade, due to it taking heavy casualties and needing sufficient replenishments.
