Pros:

Not an impossible map
New style of play like survival but quicker
Gets you pumped just like a game should

Cons:

Chopper fly's through buildings at end
Some Tanks get randomly stuck (but don't worry there are still plenty more)

Conclusion:

2 + bots You are pretty much screwed 
3 + bot You have a chance but very difficult
4 players is the way to go takes less times to win and taking it to the next level of difficulty is a bit easier

Overall I have played this map about 60 times now and it hasn't got boring yet   

Edit:
Our team beat it on normal realism 
I also be it on easy by my self and also on mutation when they only give you a desert eagle
