154th Mechanized Brigade

154th Mechanized Brigade is a unit of the Ukrainian Ground Forces.

The brigade was established in September 2023, alongside the rest of its brigade series, intending to support a plausible counteroffensive the following year.

Unlike other newly created brigades, it was formed entirely from scratch, rather than formed on the basis of an existing unit. In the early stages of formation, the brigade lacked sufficient equipment and relied in part on captured T-62 tanks and BRDM-2 vehicles to fill capability gaps.

Colonel Oleksandr Shcherbina was appointed as the brigade’s first commander and led the formation until June 2025.

In September 2024, the brigade began to receive M1117 armored vehicles, and later supplemented with T-64BV tanks and BMP infantry fighting vehicle, strengthening its mechanized components.

In August 2025, the brigade was assigned to the 16th Army Corps, a highly experienced corps formed on the basis of officers from the 92nd Assault Brigade, and concentrated in Kharkiv.

The brigade has been increasingly pulled apart, with its personnel reassigned to other formations such as the assault regiments in its operational sectors, paving way for questions as to whether the unit should continue to exist.

Insignia

The insignia depicts a chevron split in half, with a green canvas on the left, and a bright blue canvas on the right, with a yellow border nestling the chevron. At its core lies a horseshoe in yellow colours, adorned by a Cossack cross at its peak. Below the horse shoe is an arrow facing downwards in yellow colors.
