Other missions involve you being under fire for the entire patrol. You never see the enemy, just fire at the long grass in front of you as you crawl slowly to some cover. If you get up, you will be cut down within seconds, so this process takes hours. When you reach the enemy compound, if the enemy haven’t run away, dropped their weapons, and are pretending to be farmers, or if you haven’t called in enough ordnance to flatten Mexico, you will kill them in the most horrible way imaginable. That is your incentive.
Only a violent sociopath would play this game.
