Stroke German weapon (6)
I believe the answer is:
glance
'stroke' is the definition.
(I've seen this before)
'german weapon' is the wordplay.
'german' becomes 'g' (abbreviation).
'weapon' becomes 'lance' (lance is a kind of weapon).
'g'+'lance'='GLANCE'
(Other definitions for glance that I've seen before include "oblique movement" , "batsman's shot" , "Flash" , "Batsman's stroke" , "Oblique impact" .)
