well, if they don't come with guns so you can shoot them, lighter is no bad especially, if you are a precise striking Cruiser weight with military style hand combat education.
As stupid as it may sound, you strike where it hurts, but badly and this with maximum impact force. The general tactic, as you can see in Jason Bourn, is to defend and attack until a window opens to hit a preasure point like nose, eye, throught, sola plexus, kidney or groins and hit that first fast to while the opponent deals with the caused pain ever harder repeatedly yet with same precision until he or she is down or you can apply a throw against hard tarmac or any hard obstacle. Joint locks in combat crack the joint. Well trained militaries can guide the fall resulting out of the throw and crack a skull or shoulder joint by accelerating the fall instead of easing the drop forces as in training sessions combined with letting the hate go off in a controlled manner to reach ultimate aggression and directing the vulnerable bones onto the tarmac with the enemies body weight adding to the move.
But than...SEK comes with guns on meds and Rockers are not that stupid here, but both are covering theft.
