They say that something like 90% of all shootouts are won by those with the best cover, not by those who are the best shots. Can you even imagine Reese and his female partner from T1 standing against something like that? His partner was exposed for like two seconds and got blown away. I wonder what idiotic contrivance will allow them to survive.
Maybe that machine, whatever the hell it is, has also been captured by the resistance and reprogrammed. I mean it seems to be pretty easy.
