A-20B's and A-20C's had 2 .50 cal guns in the 'cheek' positions
the A-20G-1 had four 20MM cannons and the .50's
the A-20G-5 had four .50 cal in the nose plus the two in the 'cheek'
this remained unchanged for the rest of the 'G' types
the A-20J and K were again glass nose planes with the two 'cheek' .50 cal
did you want to know about rear armament also ?
