Cloth Royal Armoured Corps Badge

[GregN]

Hi guys, I picked this up in a large lot of militaria. I have the badge in white metal but I've never seen a padded cloth version. The previous collectors' note says that this is a arm badge. To me it looks like a hat badge, the idea being that banging around in a bouncing tank, smacking you noggin on all those sharp bits, it made sense to have a soft hatbadge on your head. But then again, I don't know British stuff. Please fill me in.
