Just found this link. All the patches appear to be current. I know 9th has changed theirs from what is depicted. Unfortunately for the underclass, 2010 is the only class that currently rates wearing patches on our Ike jackets, as we were the last ones to be ordered class-wide to put them on.
Some underclass put the patches on on their own accord, but word came down last semester that they weren't authorized to do so. We'll see if it changes this year.
