Supra Vijai
Black Belt
Good rooting, wear good shoes.
Read the attacker and the surroundings.
Distancing, avoidance. Be light on your feet. Of course run if able.
Make noise, yell FIRE to bring help. Crush car vindows to set off alarms. Grappling takes more time than shooting someone after all.
Strike hard, strike first if the situation calls for it, strike vulnerable spots.
Know how to grapple standing up and to break holds/ block throws.
Know how to fall, with or without an opponent on a hard surface. Use the drop to hurt the attacker.
Cross train grappling and with strikes mixed in.
There is no technique too dirty. Biting, headbutts, spitting, fishooks, slamming the attacker`s face against the asphalt etc are great. Any hard object like your cellphone can be used to crack skulls.
Know how to move and strike down on the ground outside grappling range.
Train how to get up quickly while keeping aware of your surroundings.
If I may summarise Cirdan? Basically it's "fight like a ninja "
