Special Forces: Break Out of the Border at the Beginning

In front of you, the enemy who is sniping at your comrades is right across the border. What should you do? Should we abide by discipline, avoid trouble, and watch the enemy slip away, or should we cross the border and slaughter the enemy regardless of the consequences, leaving no one behind?
