I do not know if I buy that. Commonwealth armies are far higher trained than their counterparts. They tend to be smaller, but Canada for example, highest trained soldiers around. There is a reason we travel the world and train spec ops units like the SAS and such.
There is also a reason Americans come up to take our jump course. Our jump wings are coveted and extremely hard to earn.
Maybe, but the numbers are so small, that you'd have a tough time with the rioters in Ferguson.
