The first operational use of the MRAV commenced in Maracatibe, in the context of the Theykan Security Mission in Maracatibe. Beginning the 4th of June 2016, a platoon of 4 MRAV IFVs was assigned as a reinforcement to the Ngāti Tūmatauenga infantrymen patrolling town and villages where MLA Activity was reported. The 17th of July, a column of 4 MRPV and 2 MRAV IFVs was attacked by a guerrilla cell during a patrol in a village. The column was under fire from various abandoned houses. The firepower and the protection provided by the vehicle allowed the column to retreat to safety with minimal damage, with only an MRPV being hit by a light anti tank weapon. During the engagement, 2 Theykan soldiers were wounded, while the column reported to have killed at least 5 hostiles. In the following months, an increasing quantity MRAV was employed to the mission in Maracatibe, which partecipated in many skirmishes with guerrillas, in which MRAV only took minor damage, mainly on more delicate systems such as optics and antennas.
