Travels round with some soldiers and privates (6)
I believe the answer is:
orbits
'travels round' is the definition.
(to orbit is to travel around)
'some soldiers and privates' is the wordplay.
'some soldiers' becomes 'OR' (Other Ranks).
'and' is a charade indicator (letters next to each other).
'privates' becomes 'bits' (I can't explain this - if you can you should believe this answer much more).
'or'+'bits'='ORBITS'
'with' is the link.
Can you help me to learn more?
(Other definitions for orbits that I've seen before include "Circulates" , "Whole rounds" , "Curved paths of celestial objects" , "Goes around like paths of planets" , "Travels in circular path like planet" .)
