Oh my sainted aunt, the Merlin is cool ;D
It doesn't so much go "WHOPPA-WHOPPA-WHOPP!!" like a normal heli (please, bear with me), it goes "whippa-whippa-whip!"
Erm..... anyway....
I would love to see a full brit campaign if enough addons are released (Shameless Plug....perhaps based on the novel I've been trying to write... Shameless Plug). It doesn't feel as stirring for me, as a Brit, to have defeated the commie hordes for Uncle Sam. But if we make British soldiers, we'll need extra actions such as "honk about food," "brew up" and, my personal favourite, "call the rupert a f****** c*** with your mates."
Otherwise it wouldn't be right. ;D
(That last bit was a humourous comment, and if I offended anyone, I'm very sorry and didn't mean any offence to any race, gender, institution or whatever you can think of)
