[6] In April 2014, units of the National Guard of Ukraine received their first BTR-4E IFVs, and during late May and early June they were already involved in the siege of Sloviansk, which was liberated on 5 July 2014, with the separatists and Russians withdrawing to Donetsk.

[8] Vehicles withstood enemy machine gun fire and RPGs, and the slat-armor and Kevlar layer also protected the crews from shrapnel.

The prototype is armed with the locally designed New Armament Module, which consists of one 30mm 2A72 automatic cannon, a 7.62mm coaxial machine-gun, up to four 9P135M Konkurs or Baryer anti-tank missiles (two on each side of the turret), and one 30mm automatic grenade launcher (fitted in place of the AT missiles on one left-hand side of the turret).

Ukrainian state defense manufacturer UkrOboronProm has unveiled a prototype wheeled armored fighting vehicle that is presently known as the BTR-4MV1.

[15][16][17] The Iraqi army used BTR-4s in an operation to recapture Jurf Al Sakhar from ISIL forces on 24 October 2014, successfully repelling two road-side ambushes.
