Japanese interservice rivalry crossed into real plots

How unusual were Japanese Army-Navy assassination plots compared with ordinary interservice rivalry?

The difference was that Japanese factional hostility could become serious planning and attempted action, rather than remaining frustrated mess-table talk between services.

The answer separates commonplace interservice venting from organizations willing to turn hostility into operational planning. Officers in many armed forces may complain about rival services, especially in informal settings. The Japanese case was different because factional and service conflict could move beyond rhetoric into concrete plots. That distinction makes interservice rivalry a question of civil-military stability, not merely personality or bureaucratic inconvenience.
