Judging from his grammar, I believe >>21 is Japanese.

The Japanese army doesn't look that inexperienced for combat in this clip:

However, that's advertisement and I am not a military expert.
But I believe no army on earth stands a chance against combined US military forces. Plus a lot of people in America have weapons, too - it would be interesting to see Americans get into guerilla warfare against invasion forces.
