Introduction:
Dragunov had a knack at picking up opponents as they were recovering for additional damage in DR and if you played DR long enough, it became second nature to immediately d+4,1,3 if you saw certain moves connect. Here's a list of moves that will grant a miniature combo on hit, some damage is better than no damage.
When opponent is recovering (not B!) d+2 (bobble) WS 4, d+4,4_1,3
When opponent is mid-air u/f+4, d+4,4_1,3
When opponent is mid-air u/f+3, d+4,4_1,3
