Is wearing a flag patch on a backpack against regulations?

Never wore a flag on my uniform back then

Negative depends on when wear how the flag is used. If the backpack or ruck or jump bag is part of the uniform yes. If it’s personal then no.

No

You all lost me I thought from the picture of the 25th infantry soldiers with the US flag patch on their right and the Division patch under was wrong to be displayed that way then after clicking on it we come to I guess the actual question that is asking if wearing a flag patch on a backpack is against Regulations. So which question are we discussing. SPC5

Oh yeah, the adage " You can add to, but can't take away..."

"the American flag"

Ok, so what is the answer? Yes or no? I don’t see it in all of those regs you quoted.

I’d just like to pint out to this ewho’ve references flag code that the wear of flags on our OCPs is a violation of the flag code

The uniform patch is considered a replica and as such may be worn on your uniform however since it is not stated directly whether or not it may be worn on your assault pack then it is up to your COC as to whether or not you can wear it in that manner.

I haven't seen a reg that says you can"t.
