As a guy who retired in 2014, and came back 2 year ago, "the patch" thing was... interesting. That said, it grew on me. A lot.
When I go out to the flightline, I see a lot of faces... and the patch helps remind me which ones work where... which further reminds me about "who they are" (since I don't see them that often), and helps me make a more personal connection with them.
As long as it doesn't get over the top, I think I like it. The badges everyone wears in the AF on their left breast are impossible to decipher... and simply putting what they do on these new patches allows illiterate pilots like me to appear smarter.
