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 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.
At the start of The Gardener, the player's Technician is smuggled into the Myoshinji Temple via a Kamaz truck.
At the start of Huehuecoyotl, a Kamaz carries three GI prisoners and the player's two Infiltrators disguised as GIs into a Soviet prison.
