Airborne soldier needs very large sunshade (7)
I believe the answer is:
parasol
'sunshade' is the definition.
(I know that sunshade can be written as parasol)
'airborne soldier needs very large' is the wordplay.
'airborne soldier' becomes 'para' (paratrooper).
'needs' is a charade indicator (letters next to each other).
'very' becomes 'so' (both can mean 'extremely').
'large' becomes 'L' (eg in clothes sizes).
'para'+'so'+'l'='PARASOL'
(Other definitions for parasol that I've seen before include "aeroplane" , "sunblock" , "Protection from sun" , "Sunshade" , "Small umberella for sun" .)
