A snatch strap and a second vehicle would be required to recover the vehicle. The strap is usually made from nylon as the material as they can be stretched at high loads without breaking. Winches with nylon/wire rope or chains should be attempted first, as it can be quite dangerous to use a snatch strap without knowing what you are doing. The snatch strap is designed for the initial force that may be needed to get the vehicle moving again, kind of like an elastic band.
It is important to have a two skilled drivers involved in the recovery. Make sure the snatch straps are secured to a properly rated towing point of the vehicle. Simply throwing the eye of the snatch strap on to the tow ball is not enough as it could flick off hitting the other vehicle or hurting a person close-by.
Once the strap is secured, there should be a little bit of slack on the strap to allow it to "snatch" on take off. Both the tower and the towee should select low gears (first or second) for takeoff. The towed driver must be ready in the event that the vehicle moves on the first attempt to brake if needed.
If you can't get the vehicle out on the first attempt, try again with a little more slack. Or explore other options such as digging around the vehicle or placing branches for traction.
