I can see the similarity art, but if I may enquire, I am curious about what could be perceived as a possible key difference:

Did those Filipinos fight solely in WWII in the south pacific or is there a permanent Filipino regiment in the US army?

The Ghurkas have gone everywhere from Afghanistan and Iraq to the Falkland Islands in their 200 year history with the British army.

They don't serve to protect their own homeland but have unqualified allegiance to the UK.
