You are a soldier who have recently given up work. But you left your briefcase containing very useful things back there in the restricted base. As a civilian, you cannot enter it by any legal means.So you need to enter and get your briefcase from the base. You travel at night in a simple plane so as not to raise any suspicion Your soldier clothing also helps you to camoflauge somewhat. Remember, it is a mission mostly about stealth, and know it is the army you are dealing with.

You have to escape in a tank to eveade the soldiers...and destroy the other tank in the base...lastly, you need to escape Las Vegas with your briefcase to the mountains...
Good Luck..and this is my first mission. Apologies for the mistakes!
