fringeaggressor recently came across this neat triangular piece in a group dedicated to real life military patches. It's pretty is unlikely to have been worn by any modern air force as it prominently features an F-103 Excalibur with a Confed star on the left wing. The origin doesn't immediately jump out to me either, but it's pretty darn cool nonetheless!
The following showed up in a Facebook group recently related to the F-14 Tomcat, which fits given squadrons used a triangular patch style this particular item mimics. Never noticed it in WC3, figured it was perhaps a prop item.
