Is it a knock down or a push up from Nakhimov Meal to CSM?

There were far less Nakhimov medals awarded weren't there? But it was worn AFTER the CSM in the order of precedence wasn't it?

Neither a knock down, nor a push up; the Nakhimov Medal was the Navy equivalent of the MCM, but as you say it was worn immediately after the MCM in the order of precedence.
