It even has a "Proximity Regulator".

The exhaust smoke generating system provides a self-screening smoke capability. The smoke generating system allows diesel fuel from the vehicle fuel tanks to be sprayed into the exhaust system. The fuel vaporizes and blends with engine exhaust gases. The fuel vapor cools on contact with the ambient air and condenses to form a homogeneous smoke screen. The system is ineffective when JP-8 fuel is used.
