Is wearing a flag patch on a backpack against regulations?

No it isn't against regulations. But you may wish to find another hill to die on.

I think and as always up for interpretation when is says The US Flag should never be worn refers to using a real flag as a make shift shirt, undies, pants etc. I do not see where it says Images of the US Flag. The USFC is and i hate to use this cause it will cause a problem at times. Is like the Bible or any other religious book. It is open for Interpretation One NCO may see it different then a CO, so on and so on... I've been one for the simple "unless it was issued to me i really don't use it or bring it."

Flying a flag in a war zone is regulated. Slappiing one on an ass pack is very different.

We'll now, nice comments everyone. My 2 cents, while in the military unless in times of war we are not allowed to raise the flag on foreign soil, even then that means we have conquered which we only liberate today. As far as patriotic displays, I'm all for it as an individual but as a unit. I think it is not appropriate as when in the military we represent All of the U.S. just my thoughts.

As with many things in life, attitude and respect mean more than the letter of the law.

Yes

If you are in uniform and wearing an authorized pack, technically that pack is in uniform standards and should be treated as such. So a flag patch attached to it should not be an issue. It's a gray area though, so sometimes it's best to do what's told.

If it is I'm wrong. I wear a flag on my backpack when I'm doing excursuses with ROK in Korea. I also have my branch so our guys know, but unfortunately my branch is so knew most of our guys thought I was signal.

No. As long as it is not facing in a retreat fashion

No it is not just do your best to keep it clean as much as you can
