Why are the army still using radios to communicate? Most mobile phone networks have excelent signal cover these days and are usable in most places. Also, if you were all on Orange, for example, you could phone each other during missions and get extremely good rates. Also, if it was a stealth mission and silence is important, then you could txt your message as opposed to shouting down a radio and alerting the enemy to your presence. So, will the mobile phone ever replace the radio? I for one think that it should. And soon!
