filthy,racist, death sellers! :mad:
and yes I know it is a fake ad, but still… 
Way back when, about 57 - 59, a friend and I would take our .22 semi-auto pistols and our Nylon 66 Remington .22 rifles out to the strip pits East of Tulsa along with a lot of the big glass votive candle ( orange and blue ) jars that had been used at the church. They were real easy to tell if you hit them. 
We then would go through a brick each of .22 ammo play and practicing all kinds of stuff. We did a lot of shooting while running and the most fun was when we would roll down the sides of the pits shooting every 1-2 rolls ( like a log rolling down a hill ) shooting at those jars. We learned d how to keep the gun in a safe position as we rolled over it, gained a lot of experience with situational awareness, as we would both be rolling at the same time and shooting at the same targets. )
We used boxes and junk to make shooting towns and lanes long before I ever saw one in a movie or film.
We practiced speed shooting in various guises and used a stop watch to time each other on how long it took us to get into action form various starting positions including getting out of a car and returning fire as fast as we could.
I did lean some non standard ways to shoot and I had some trouble in the ARMY in basic until the Captain looked at my scores and then he made the instructors go bother the guys who could not shoot at all. I could do all the ARMY stuff but did better with some of my self learned ways under certain conditions.
When the shit hits the fan, most folks revert to their oldest and strongest habit. That is why constant practice is needed and even more so if you are trying to break an old habit.
Can’t go play like that now, got to go to ranges and just do it like you are told.
Paint ball is not live fire and until you have been vibrated off the ground with a .50 cal machine gun shooting real bullets 18 inches over your back, well, you just been playin.
YMMV
There are some braced handgun stances where you have one upper arm against your chest to provide for support and stability. You would normally only do this for slow fire in a shooting match. Most situations involving pistols in real life wouldn’t call for it. and then you’d probably be better off kneeling.
I’ve only used a braced position when I was shooting a Thompson/Center Contender single-shot scoped pistol, but I imagine at some point someone may have used a braced position with a revolver or an automatic pistol.
I hate to be the one to tell you this, SS, but they aren’t telling everybody about how cool it is.
They’re telling everybody about how cool YOU are for doing all of that!

Do you still get offended over ad parodies, Mr. Falwel?
