The machete is seen in the American levels on Roebuck's back. Other Marines also have machetes in their character models. The machete is also seen in the Soviet campaign being used by Sgt. Reznov in the levels "Blood and Iron", and "Downfall". In the level "Blood and Iron", the machete is held by Reznov at the end of the level, just before the player gets on the train. In "Downfall", Reznov uses the machete to kill a German soldier who shot Dimitri Petrenko. Reznov jumps towards the German, slices, and stabs his victim with the machete, then kicks him off the ledge. He also used it to cut off the Nazi flag. This is the only time in the game the machete is used to kill a character. The machete isn't used at all in the American Campaign and only appears on the character models of some marines.
The machete is seen being used by a member of the African Militia in the level "Back on the Grid". As Yuri runs from the militia, he falls through the roof of a shack and is faced with a man armed with the machete, the man attempts to attack him but is shot before he is able to reach him. The machete is unusable, just like the previous games.
