Not to pour water on the thread... but it's not very realistic... Unless your a cartel leader, or a Afgahni war lord... A large fortified complund in an urban setting, with guards? who by the way are all dead? I'd trade all the above for a secure escape route. The fight is already over.
Sorry... just my opinion.
You got to know when to hold em
know when to fold em
know when to walk away
know when to RUN!!!
