Ivan Petrovitch (Russian: Иван Петрович) is a major Ultranationalist leader in Call of Duty 4: Modern Warfare (Nintendo DS). He is also the only antagonist to appear in the game, while the rest are only mentioned.
Petrovich was one of the key figures involved in Al-Asad's military expansion in the Middle-East; His role was to send nuclear weapons via cargo ship. He spent most of his time in his mansion in the Caucasus. In the level "The Russian", Ivan is captured by the SAS agent Snowman when his spec ops team assaulted Ivan's compound at 4:00 A.M. When he is interrogated by the SAS, he leaks information about enemy documents inside an Ultranationalist bunker. When Bravo 9 completes the mission to retrieve the documents, it would later point to a missile launch facility. After further interrogation, Petrovich finally gives off the position of the nuclear device from the level "Intervention", which Bravo 9 and his squad failed to secure earlier in the campaign. After these events, he is never mentioned in the game again.
- The model files refer to his models as
"zakhaev", possibly showing that Ivan Petrovitch was intended to be Imran Zakhaev.
- Petrovich's model is presented as a hard object in "The Russian" which explains why he can't die.
