Chains are for tying down equipment when hauling. Chains are designed for static loading. Not for shock loading, such as when used to jerk on anything. There are correct types of recovery straps for that. However, the best plan of attack, to reduce the damage risk to vehicles, or folks standing in the kill zone. Is the good old fashion worm gear drive winch. Gear drive winches produce a slower line speed. And more often than not, have a much lower gear ratio than other type winch drive system. Safety is more important than speed when moving any object that has became part of the ground. Carry a couple of 4 ton snatch blocks, tree saver strap, a 6"X30' recovery strap, 4 ton rated shackles, a pair of heavy duty wrecker style chock blocks, a high lift jack, and a round point shovel on your rig. With just that small amount of recovery gear, and knowing how to use it correctly. You will not be calling folks to get you out. It will quickly become you, that are being called to get others out. Semper Fi. OUT!!!!!
