PURPOSE OF USE
The battalion command post on the chassis of MLI-84M is meant to equip the infantry battalion on MLI-84M as it is used for the direct driving of all vehicles in the battalion’s fleet and for the ensurance of the liaison with the command post of the brigade.
The battalion command post on the chassis of MLI-84 M is a tracked vehicle, resulted further to the execution of a proper superelevation of the basic vehicle’s armoured housing.
The crew of the battalion command post on the chassis of MLI-84 M consists of 6 people, including: mechanical-driver (at the driving post of the vehicle) and 5 members (in the work room).
PCB MLI-84M is equipped with all the equipment needed to fulfill the combat missions. It can provide at any time the data regarding the subunits it manages: data on the order of battle and its condition, on the possibilities of firing, on the place of action, on the missions that are executed, on the needs of the subordinates, on the degree of material, on the technical and medical provision.
