Although Kamaz trucks often appear in skirmish maps as civilian units, they only serve gameplay-related purposes in the campaign, either as a map objective or as a transport for specific units or other objects. The Kamaz is never buildable as a unit and has no use in combat, not even crushing enemy infantry.
In Archetype, once Boris and Morales locate the AlliedTech Center where the bodies of Volkov and Chitzkoi are housed, the bodies will be loaded onto a Kamaz truck. The truck must then be driven by Morales to the designated extraction point (it cannot move if Morales is not inside), while being escorted by Boris.
In Warranty Void, a peculiar Kamaz truck can be found east when the player's forces approach it. The truck will be shaking uncontrollably due to the captive within.
In Heartwork, once the Russian forces reach the farthest Nanocentrifuge, a Lancer prototype will enter a Kamaz and attempt to escape. Both the truck and the Lancer must be destroyed by the player.
In the Covert Ops mission Brothers in Arms, once three Nuclear Reactors is destroyed, Reznov and Krukov must board a friendly Kamaz among Epsilon convoy to get into the city in order to destroy the rest of reactors.
In Cyberanatomy, once Krukov and Reznov have achieved all of their objectives, they must be brought to a Kamaz truck to evacuate.
