I see your point. However, don't you think that the task of a lost soldier to get back is the same of a lost person? The difference is that the surviving person can be searched to be rescued while a soldier to be captured by the enemy and rescued by his fellows. And it seems to me that if people get into survival situation they would prefer to get out of it as soon as they can and would not have enough time for any delays, except situations when there is nowhere to run. I read somewhere suggestion that if you get into survival situation, you should not rely on possibilities that you will be rescued, but should try to get out by yourself. Regards,
