Identifying regiments

Hi, the attached pic shows two of my uncles centre and right as you look at it.
My uncle Doug on right was in the Gordon Highlanders, can anyone tell me what regiments my uncle Bill in centre and unknown chap on left were in please?

 

Will have to work out how to reduce size of photo file!

can't enlarge image all I get is a white square with timer circle.

 

Sorry I've just attached the only photo I have - see it - twice for some reason. View attachment 24051

 

edit: sorry not too good on Scottish Regiments.

if you have date of birth & full names , I'd send off for service records from MoD

 

Possibly Argyll ans Sutherland regiment

 

thanks Owen
