snowaterskier

I recently purchased a new twentysixteen Outback AWD, I head into the mountains regularly and have always had tire chains with me for security. I have been told that damage can occur if tire chains are used on a AWD Subaru but have not found any cautionary statements on this forum. I put new Blizzak snow tires on so I am not anticipating having any issues but I have personally witnessed a 36" dump while I was skiing and was glad I had chains to get my vehicle out of the parking lot and back to the mountain condo - the plows just simply cannot keep up with this type of snow event. Question 1). Will damage occur to the transmission or brakes or anything else with limited use of proper fitting tire chains? 2). My instinct say's to put the chains on the rear two tires, is this correct? 3). If the answer to question 1 is a resounding YES, then another idea I have if I get stuck is to simply place the tire chains laid out in front of the rear, or front, tires so that I can drive up on them to gain traction and up and out of whatever I am stuck in without actually placing them around the tires, (This however would create more traction on some wheels than others which may lend to transmission issues).
