I'm not sure if this is just poorly worded or if you're confused how helicopters work.
The turbines in a helicopter provide almost no thrust directly. Ideally, 100% of the power that the engine produces is transmitted to a shaft that goes to the helicopter's gearbox. A very small amount of thrust will happen as a side effect because typically the engine's exhaust is pointed towards the aft end of the helicopter. Compared to the amount of forward thrust the helicopter gets from adjusting its main blade the effects of the exhaust are extremely minimal. This is why this kind of engine for helicopters is called a "turboshaft" engine, the power is transmitted out through the shaft. The same style of engine powers the M1 Abrams tank.
Other kinds of turbines, like turbojet and turbofan engines are what people would refer to as jets because they dump as much power as possible into the air that they are shoving through (or mostly through a bypass duct in the case of the turbofan) the engine which then is shot out the back as a jet of air to provide the thrust. You usually wouldn't classify a turboshaft engine as a "jet" engine because it's not designed to create thrust by that jet of air coming out the back.
As a historical side note the engine in the M1 Abrams had actually been developed into a flight weight engine to power the Blackhawk and Apache but lost to GE's T700. It's suspected that they military chose GE mostly because of political reasons. The company (Lycoming) producing the M1's engine already had contracts for a huge percentage of the turboshaft engines being sold to the military at the time in many different vehicles.
