Ohholyshit, so much wrong here
First of all, in engineering terminology, there is no such thing as a jet turbine. The jet engine
uses a gas turbine
to propel a vehicle. The high energy gases which exit from the turbine stage of the gas turbine (which is actually a compressor + a turbine+ a combustion chamber) push the vehicle forward. Jet engine have only a few turbine stages to drive the compressor.
Abrams is not
a jet-powered tank. It too uses a gas turbine, but this time the gases which exit the combustion chamber pass through several turbine stages and the kinetic energy is extracted from a shaft (turboshaft engine).
I mostly associate piston steam engines with steam punk, because the steam turbine is not that clacking, steam belching kind of machine that I think fits the genre most.
