Gloi arayos (can’t discuss it on YWN – it rarely happens except in wartime – unlikely to occur to a soldier in a modern army)
Avodah Zarah (particularly if done in public)
Spilling blood (e.g. if a doctor was order to perform an abortion and threated with death for disobeying – not an everyday issue)
However on all the things that one must give up your life rather than violate, just because you arent’ threatened with death doesn’t mean to ignore them – it means you should be very willing to give up your parnassah to avoid them, since Kal ve’Homer you would be required to give up your life to avoid doing them.
