From what I've heard, the red triangle is the civi version. If it has the "O-Metal" Oakley logo on it, then it's the issue version.
That's what I "read on the internet", although I've walked into O-Stores and found the SI boots with the metal badge rather than the red triangle.
PS, a huge factor for me to get the tan version of the Oakley SI's, is because the badge on it is GOLD.
*pimp*
