Small camera initially reveals people on patrol (6)
I believe the answer is:
scouts
'people on patrol' is the definition.
'scouts' can be an answer for 'people' (scout is a kind of person). I'm unsure of the 'on patrol' bit.
'small camera initially reveals' is the wordplay.
'initially' suggests taking the first letters.
'reveals' becomes 'outs' (outing is a kind of revealing).
The first letters of 'small camera' is 'sc'.
'sc'+'outs'='SCOUTS'
Can you help me to learn more?
(Other definitions for scouts that I've seen before include "Lookouts or pathfinders" , "They're sent out to get information" , "Spotters" , "Goes ahead to get the lay of the land" , "Persons sent out to gather information - may be boys" .)
