Well, one, Roy is in the Guard, not in the mount. So yes, in the hierarchy of positional dominance, he is one up from the mount and has control of his opponents hips. So yes, indeed "possible".

However, have you ever really tried an arm bar from the guard on a fully resistant opponent? Especially one that is bigger than you? Probably not the smartest thing to attempt on the street.

I am a purple belt in BJJ and compete internationallly, I don't get these but every so often, AND we are not allowed to hit, AND we are segregated by weight class, have nice mats, gi's and are rewarded for fighting on the ground.

That said, as a teaching tool, the Arm bar from the guard is a wonderful thing to teach. It teaches you many things that are much more important than getting the arm bar itself.

This is one of the basic techniques we start teaching at the white belt level. Why? not because we expect that students will readily be able to go out on the street and use it, but because it starts developing the ability to move the hips.

Watch the video carefully and you will see that the very first thing that happens in you break spinal alignment by underhooking the leg and moving your hips off to the side. This serves to off balance your opponent (principle of irimi) and his weight is no longer going straight down on you.

More often than the arm bar, you are able to execute a sweep and put yourself in a more dominant position, which allows you to more better control the guy and possibly escape or apply chokes, or by time.

Being able to do this, however, takes a fair amount of practice to develop the skills, the attack chains, and the timing to be able to execute jiujitsu from the guard. It is why we BJJers spend so much time in the Guard.

From the guard for a self defense perspective, I would tend to teach cross collar chokes, strikes, shrimping skills, and teach them to stand up in base once they created distance, way before i'd spend time on teaching the Arm Bar from the Guard as a method of self defense.

Again, it is a good base technique for learning JJ fundamentals, and is an excellent foundation to build attack chains upon. As a money maker....not likely for a female being over powered by a guy...too technical and way too much risk involved, and there are many other things that should be taught first that are more "high percentage" and safer.

Wrist locks, arm bars and such might be useful in buying you time or creating a space in the fight, however they don't typically end a "real" fight or rape, they tend to piss the guy off more.

However, a good blood choke executed shuts things down. I'd put my money on establishing a position that I could execute a blood choke way before ever using an arm bar.
