Maker of uniforms possibly to follow common soldiers (6)
I believe the answer is:
tailor
'maker of uniforms possibly' is the definition.
(a tailor might make uniforms)
'follow common soldiers' is the wordplay.
'follow' becomes 'tail' (both can mean to chase or pursue).
'common soldiers' becomes 'or' (military abbreviation for 'other ranks').
'tail'+'or'='TAILOR'
'to' acts as a link.
(Other definitions for tailor that I've seen before include "Maker of clothes for men" , "One makes suits etc. to measure" , "Garment maker" , "One makes fitted clothes" , "Outfitter" .)
