The Vietnamese, Cambodian, and Laotian parachutist badges are all similar in that they are patterned after the French wings because all three were once a part of the French colony of Indochina (
Indochine Française).
If you look at the various parachutist badges throughout the world, you will find a similar pattern of their being copied from those of the major powers with which they were aligned, especially those influenced by France, Great Britain, and the USA.
All that being said, I'm still curious as to how Mr Dye came about wearing the ARVN wings.
