AADs are not required at VSC for licensed and current jumpers, but we highly recommend the use of AADs and RSLs for all jumpers, (with very few exceptions, like CRW guys and RSLs).
Trust me I wish I had an AAD on the rig I was borrowing. When I started buying gear the AAD was my first purchase. But that AAD is sitting at chutingStar waiting on my container to show up.
