Finally, Berlin is assaulted and close quarter fighting becomes a common feature. After that, combat occurs in farmland and forests of the German town of Seelow, including using a T-34 tank to smash through German defenses. Combat takes place, at first, in the ruins of Stalingrad where the player is mainly a sniper. In the Russian Campaign, players fight against the German Wehrmacht during the push towards Berlin. The player must also fight with a crew of a PBY Catalina Black Cat. Bunkers are a common sight in the American campaign, usually causing heavy casualties. Combat also takes place in small mortar pits, ridges, beach heads, Japanese trenches, and small villages.
Most combat takes place in jungles, where ambushes are likely. In the American campaign, players, for the first time in a Call of Duty game, fight against the Japanese Imperial Army.
