FAA aircraft with US markings - Torch Nov 1942

[Leendert]

Just curious. Most, if not all Fleet Air Arm aircraft engaged in Operation Torch had US national markings applied. This to prevent confusion between British and French roundels and also and perhaps more important because it was thought the (Vichy) French were less keen to oppose the US than the British.

Reasons aside, are there more such Allied operations known where this approach was used with other national markings on aircraft?
Here I exclude the foreign squadrons operating under the RAF umbrella, and secret ops.

I gathered that under war law it's not accepted to fly the color of a neutral state or party not engaged in the conflict as a ruse, so Torch fell within limits? But that's more a question for any lawyers among us...

Thanks for any info.
