Just for information, the difference between max reheat and combat is that when combat is selected, the TBT (actually SOT) limit is raised by 30k. This is sometimes confused with the war and peace switch which is different. The pilot can select combat as well as selecting the TBTRSS switch which is normally set to low and has a thin tell tale wire to show that the switch has been moved. The switch when selected further increases the SOT (stator outlet temperature). These temperature limits are set in the MECU as the engines are (normally) temperature controlled with TBT read by the optical pyrometer. Yes, the detents are ball bearings.
