What insignia does the current Naval Infantry wear on their uniforms? Do they wear the appropriate Naval Fleet patch or the standard Armed Forces patch?

Also I've seen several variations of the Naval Infantry patch. In addition to the standard Naval Infantry patch I've seen variations for Naval Infantry based on their fleet or specific Unit. Are these authorized and if so where are they worn?

In the Soviet Union the patch was worn on the right sleeve. In current photos I've seen it worn on either sleeve.

Does the Naval Infantry wear Navy rank insignia or Army style?

Any help is appreciated.
