For example, soldiers are about to appear (6)
I believe the answer is:
emerge
'appear' is the definition.
(emerge can mean to appear or arrive)
'for example soldiers are about' is the wordplay.
'for example' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'soldiers' becomes 'reme' (Royal Electrical and Mechanical Engineers corps).
'are about' shows that the letters should be reversed in order.
'eg'+'reme'='egreme'
'egreme' in reverse letter order is 'EMERGE'.
'to' is the link.
(Other definitions for emerge that I've seen before include "Suddenly appear" , "Become gradually apparent" , "Come out or become known" , "Come out or transpire" , "Materialize" .)
