The 25acp of the tussleing world, I compare the two because they are thought of as puny attacks and easy to survive, but they amount for a fair amount of street kills.
A Real two hand Front Choke can be a skilled neck snap, or a vicious crazed attack, lifting your body off the ground or forcing you to the ground. We train in the begining as a basic principle (with multiple counter moves to the attacker being on the ground) that grows into various (if that don't work) counter drills. At the intermediate/advance level its trained with vicious realism. We train it at four ranges "Instants before the grasp", "The Grasp before the arms bend", "The Grasp at full choke, armed bent" and the SOL "Choke mounted". The counters are full intent and as vicious as the attack, I train this as attempt upon your LIFE. This may shock some but we trained the SOL choke with deadly force attempts. Double thumbs into the eyes or if you followed the class be prepared strategy. Get your knife out and stab him in the temple, cut his arm joint, stab/slash under his armpit and then cut hsi jugglar with the blade bc you are SOL.
This is an attack of a Desperate, or skilled or Crazy person, it is an attempt on your life.
I had a begining (really smart academicaly) 13 yr.old kid 8th kyu ask, "why train to defend a 2 hand front choke?" I told him "you will more likely have to defending against a 2hfc then a flying side kick on the street." Trust me this is vital, if or when you need it.
