- "Don't worry, I've brought some friends."
- — John Price referring to the resistance.
The Czech Resistance is an allied faction that appeared in the Call of Duty: Modern Warfare 3 campaign. Given its identity, this faction was formed when the Ultranationalist government under Makarov's influence switched tactics to conquer Europe, especially Czechia. The Resistance was formed mostly of the country's local civilians, who attempt to fight back and repel the Russian invasion, but they take heavy losses against Russia's vehicles and from their lack of anti-vehicle weapons.
Call of Duty: Modern Warfare 3
The resistance helped Task Force 141 and Loyalists to hunt Makarov in their country. They were first encountered in the mission "Eye of The Storm", where they help badly wounded civilians and resistance members. They helped Price, Yuri and Soap (who was badly injured) by defending them from Ultranationalist attack during "Blood Brothers". They also appear as civilians in the Spec Ops mission Resistance Movement.
- Strangely, the Resistance members seem to be voiced by Russians instead of Czechs, which is evident by the fact that they all speak with a very thick Russian accent, often mispronouncing the words.
