To say it's propelled by a gas turbine is a little misleading and implied it's a jet tank of some sort.
No it's not, unless you think it's also misleading to say a car is propelled by a piston engine. Is a car propelled by its tires?
*Edit: added required negative
I don't think it is - the power pack is a turbine which is connected to the drive. If you look at cross sections you can see it doesn't contain pistons.
