Communication experiences during a mission in Afghanistan

In this short treatise, I tried to share my experiences about the possibilities of modern communication means in a military mission in Afghanistan. Instead of describing the devices and equipments in details, I intended to focus on networks and systems from the point of view of a common user. I am presenting the systems in the way of making two big groups such as telephone systems and informatics networks. Following this line, I tried to draw a general overview on networks that can be found in a mission in Afghanistan by soldiers. I also wanted to show just some main principles that should be followed when maintaining secure network.
