“I don't think we'll regret that we blew that bridge up. 'Cause you never know if they would like to send here a couple of tanks... it could be a pain.”

even if it's more correct, i still don't understand the thing with the tanks.
is the narrator saying that they wanted to send tanks on the bridge and now, they can't anymore because it's destroyed? and it could HAVE BEEN a pain if they have sent them?

or am i wrong?
