If you are working with a military then you need to keep your time check the entire time since these guys are so punctual and would be irritated if you can't comply with their standards. These guys are trained that way, so they would be reliable when the time comes that their country needs them. In the battlefield, you need to be punctual since there are bullets flying all over and one mistake could be your last. That is why, those army guys are always punctual in almost all they do because they have been trained to be that way. In this game, you are the truck driver and your job is to deliver some men to the outpost. No, you can't make any excuses on why you are late and you would get some punishment. Fortunately, this just a game and you won't be punished, but, still you can't get to the next level if you are not able to make it on time. The time limit is very short that you need not to waste any of your time or you won't make it at all. The game would be harder as you make some progress.
