1. An assembly for a turbine engine, the turbine engine having an engine core comprising a fan section, a compressor section, a combustion section, a turbine section, and an engine drive shaft operably coupling the fan section, the compressor section and the turbine section, the assembly comprising:
an accessory gear box (AGB);
an air turbine starter (ATS) having an ATS turbine, an ATS gearbox, an ATS drive shaft operably coupling the ATS turbine and the ATS gearbox, and an ATS output shaft operably coupling the ATS gearbox to the AGB;
a bleed air turbo (BAT) including a BAT turbine, and a BAT output shaft, the BAT output shaft being operably coupled to the AGB; and
a bleed air circuit comprising:
a first bleed air passage;
a second bleed air passage fluidly coupling the first bleed air passage to an input of the BAT; and
a third bleed air passage fluidly coupled to an output of the BAT;
wherein the BAT output shaft is driven by supplying a working fluid to the BAT through the second bleed air passage, the driving of the BAT output shaft supplying a mechanical input to and at least partially driving the AGB.
