Bombard faster, somehow (6)
I believe the answer is:
strafe
'bombard' is the definition.
(strafing is a kind of bombarding)
'faster somehow' is the wordplay.
'somehow' is an anagram indicator.
'faster' anagrammed gives 'STRAFE'.
(Other definitions for strafe that I've seen before include "Spray with gunfire" , "use machine-guns" , "Blast, shell" , "Set RAF to attack with gunfire" , "Attack with fire from a low-flying plane" .)
