I missunderstood. Red wings were completely different in my day. Red, Brown, And if you were darring enough there was even gold. 
Heeheehee
For anyone who doesn't know, Mthrockmor was referring to a tradition in the airborne, where when your jump wings are pinned to your uniform, the pinner punches the wings into your chest, driving the two spikes on the back of the badge into your skin. This of course causes some bleeding and hurts like hell, which is how the term "blood wings" came about. The tradition is more & more frowned upon by today's sensitive brass in charge, since it causes some pain, and we don't want our warrior's to experience any pain or any awful thing like that. Even so, it's still practiced behind closed doors. Hooah.
