Is wearing a flag patch on a backpack against regulations?

i dont know but i always bcarried a real one in it

Yes

Yes because the flag is to look like your are always moving forward

This is all about interpretation. We wear the flag on the right shoulder. As much as I agreed with most of the responses here, I have to remind everyone that when a Soldier is down to the ground after an attack, etc... that flag will touch the ground, the floor or the water, depend on the situation. Now I will not attach my flag to a backpack nor a rucksack, but that is just me. And not, there is not such thing in any regulation. Maybe a CDR policy letter.

It shouldn't. Be.

Not knowing ARMY regs, I can't say. Personally, according to flag etiquette, I'd say it's fine to attach it to a back pack. Just my opinion, but if you disagree, that's fine.

yes

yes

no

Military and Civilian norms are different, so is the time period.
When I was active and in the Reserves US Flag patches were part of the uniform, now that I am Civilian and a member of the American Legion Riders, it is almost required! THANK GOD!!!
