This is a Sambo technique that will not only get your opponent down to the mat but can put you in position to end the fight with a knee bar or knee slicer.
In this video Scott Sonnon goes over a technique that he calls the Seatbelt Roll.
You start from a two-on-one or Russian Tie and then reach over your opponent's back as you step your leg onto your opponent's thigh as high as you can.
Scott adds the detail of scooping under your opponent's knee as your roll to take them down. This is going to help you secure the position instead of jumping for a flying scissors and hoping you land it.
