Nice patches. They have "job title" patches for all kinds of stuff and different versions of them too. I have some but I don't have access to them right now.
I was just looking through my photos and saw one of a guy wearing that exact Armor patch. I know for a fact though that the closest thing he had to a tank was an old Humvee. I have one of those patches too. It actually phonetically spells "Tank" at the bottom and says "Allahu Akbar" at the top. Not sure if its actually meant for real ANA tank units or not but I know the ANA I was with would get these patches from bazaars and if they liked what it said or looked like, they would wear it. Didn't matter if they weren't Commandos, Snipers or didn't have a tank. Whatever they though was cool was what they wore.
