why is CON rank is Radm?
is the rank higher that MG or COL?
U have Rear Admiral (1 star), Rear Admiral (2 star) and Vice Admiral which is equivalent to 3 stars. Both Rear Admiral ranks are obviously bigger than COL. If u asking why it is called rear admiral, then I think U can search google for the history behind it.
chief of navy isn't con. its cnv.
