True / False: The four types of smoke are obscuring, marking, incendiary, and deception.

The statement that the four types of smoke are obscuring, marking, incendiary, and deception is not accurate, which clarifies why the correct answer is false. In military operations, smoke is primarily classified into three main types: obscuring smoke, which is used to conceal movement and operations; marking smoke, utilized for designating targets or areas; and incendiary smoke, which creates a fire hazard or serves a tactical purpose. Deception smoke is not typically recognized as a separate type; instead, it might loosely refer to tactics involving smoke but does not stand as an official category in the classification of smoke types. This distinction is crucial for understanding the application and purpose of different smoke types in military contexts.
