Myanmar (former Burma) Patches

[Badger44]

Do any of our very knowledgeable forum members know anything about the patches worn by the Myanmar Army? Or can anyone point me in the direction on any identification possibilities?
I have just bought 23 patches which I am told are from this country. I confirmed this on the internet as there are photos of Myanmar troops in parades, some of which are wearing some of them The units are not however identified.
Some may be generic i.e Artillery, Medical, Armour etc, but if anyone knows any more specific unit or formation identifications, I would be most grateful. I have attached scans of all of them.
Thanks or any help.
