They say that once you joined the army, one of your foot is already in the grave pit. Your life is always in danger because enemies wants you dead while officers would let you go first as they don't want to go first in a war situation. That is the truth about the military. Your job entails you to deliver some nuclear weapons to next base. You know that this would be dangerous, but this is what you sign in for. There would be no turning back for you as you don't have a choice here.
Drive your truck as fast as you can till you reach the base. You are carrying a nuclear weapon, so you can't take your job lightly. Try to balance your truck all the time, so your cargo won't fell off. The path ahead would give you a tough drive as there bombs and the road isn't straight at all. There is no timer in this game, but it is a good idea to have a momentum to be able to get far in the game. It is not a requirement, but it is necessary for you to be able to reach the destination point.
