Rank Slides

I've seen pictures of sailors/officers wearing rank slides with a white rectangle on them and I was wondering if any of you could clarify what rank these portrayed?
White Rectangle on its own?
White Rectangle with Sub-Lieutenant Rank slide?
White Rectangle with AB Rank slide?

Thanks

 

Under Training.

Not seen a rating with a white flash, must be a more recent variation.

As a Specially Selected Marine Engineering Mechanic, we had a red flash over the name badge on out eights (Fours) and there used to be orange shoulder flashes for "phase one trainees", green for phase two. (Ratings).

 

Did'nt Upper Yardsmen have white flashes?

 

Pt4 chock heads were the first I've seen with the white rectangle below the AB rank slide. Otherwise it's worn by officers who haven't completed their fleet boards, generally known as bullet proof shit deflectors!


It was like that when I found it chief

 

All Phase two trainees at Collingwood have white tabs on their epaulettes

 

Add Raleigh to that list for Phase 2's, but stand fast Sultan.

 

As others have stated "under training" - officer cadets and ratings in phase 2/3 training at various bases will wear these to denote they are still under training.

 

Specially selected candidates are permitted to wear 'Brown Wings' on their uniform.

 

And rightly so SgtP, but what about the less frequently observed Red Wings?

 

Green Wings, Blue Wings and don't forget the war stripes

 

Ooh, there's posh, boyo.

I never knew that. Do we knit them ourselves or are they pattenised?
