Is there data about how the mode of a states army affects the probability that it is employed against its own people? I mean is it more liklier that the army is used to supress the own people or a certain group of people when the army is based mostly on career soldiers or long term conscripts? And will the probability decrease when most conscripts will only enlisted for a short period?
Is there research whether the length of mandatory military service affects the probability an individal will refuse immoral or illegal orders?
Also thinking about whether it affects the probality of a coup or a revolution, and whether the army will beat down uprisings and revolution.
